This is a partial list of terms relevant to ultimate:

Bid

An attempt to catch or block the disc, usually a layout or sky.

Bomb

When one team has control of the disc close to its own endzone, throws the disc (to nobody) toward the other side of the field. Used to stop or to reset the advancement by the enemy team toward the "Bombing" team's own endzone. See also Punt.

Break

1. A break-point is when the team starting on defense causes a turnover and scores.
2. To break your marker means to throw the disc past them to the side of the field they were trying to deny as part of a force defense.
3. A break-force throw is one that breaks your marker.
4. A call of "no break!" is an instruction to the defensive player currently marking the disc not to get broken, and is usually called when an offensive player gets free on the closed side of the field (and would therefore be easy to throw a break-force throw to).

Brick

A pull that initially lands out-of-bounds, untouched by the receiving team.

Callahan

When an opposing team's pass is intercepted in their end zone, scoring a point for the intercepting team.

Cherry Picker

A player who stays near his team's scoring zone to remain open to a bomb pass.

Chill/be Chilly

Used to urge a player with the disc to have patience and not throw the disc too quickly. Phrases like "take your time" are avoided, since they could be mistaken for the act of calling a time-out.

D

Short for defense; the defending team is on D. A D can also refer to a defensive play: "He D'd the disc in the endzone."

Darsh

The act of easily knocking a disc out of the air, usually directly into the ground, and with strong force. Typically done to make fun of the thrower or receiver.

D-Line

Players who are assigned to be on the field whenever play is started by that team launching the pull.

Double Happiness/Bookends

When a defender makes a defensive block and then scores a point on the ensuing possession.

Double Unhappiness/The Books

The direct opposite to the above. When a player's throw is blocked or hits the ground and then the resulting offensive play against him results in his mark scoring on him.

Dumping/Dump

A throw to a person in the dump position (usually an offensive player close beside or behind), used for resetting the stall count to prevent a Turnover.

Foot Block

When a defender knocks a throw to the ground immediately after it is thrown by blocking it with his foot.

Force

The direction in which a person who is marking tries to force the handler to throw. Alternatively, the marker can try to force the handler into a specific type of throw, e.g. 'force flick.'

Greatest

A technique performed when a player breaks contact with inbound territory and redirects the disc in an attempt to keep the disc from touching the ground out-of-bounds, hence keeping the disc in the field of play. The "greatest" greatest would occur if the throw were caught in the endzone for a point.

Handler

Either the person currently with the disc or players designated to "usually" have the disc (especially used when playing against a Zone defense).

Hell Point

A point that takes an inordinate amount of time to complete, usually due to excessive turnovers. Because substitutions are only allowed between points, the players on the field become tired and 'in hell'.

Hospital Throw

A throw that stays in the air for a considerable amount of time, allowing multiple players to get under the disc, and therefore leading to a greater chance of injury.

Huck

A long throw, generally at least half the length of the field, generally to a downfield receiver. Contrast with 'Bomb' and 'Punt', which imply the voluntary decision to lose possession to move the disc down the field.

Kick-Catch

Kicking the disc with the foot in order to move it up and then catching the disc with the hand.

Layout

A dive to catch the disc.

Mark

To try to hinder the throw of a person with the disc by blocking possible avenues of release using the body or arms (no physical contact is allowed). Also refers to the person in the act of marking the person with the disc.

O

Short for offense; the team with the disc is on O.

O-Line

Players assigned to be on the field whenever play begins by that team receiving the pull.

Poaching

In man-to-man defense, the act of defending an area of the field instead of one's assigned man. This will inevitably leave someone open, who is said to be Poached.

Point Block

Blocking a disc that has just been released, resulting in a turnover. Also known as a Hand Block. Known as a Foot Block when the block is made with either foot.

Pull

A long throw that initiates the start of play, similar to a kickoff in Football.

Punt

A throw that is launched downfield to force the opponent to begin play further downfield, often thrown at a high stall count when no other choices are available. Taken from American Football and Rugby, where a 'punt' is a kick downfield.

Rickel

When a player makes a difficult catch which is immediately followed by a very poor throw. Also known as the Law of Conservation, Conservation of Greatness, or the Rule of 11

Scurvy/Scurvy-Dog

The act of faking out the marker so badly that he yells 'up' while making a full revolution in place while trying to find the disc that is still in the thrower's hand.

Sky

Leaping and catching the disc at maximum height over an opponent - a tactic that leads to immense gratification for the skyer and great embarrassment for the one who is skyed. Also referred to as a "Tea Bag" or "Box Lunch" depending upon the gender of the skyer.

Snake

When a defender craftily intercepts a pass by reaching over a shorter offensive player or breaking to the disc at the last instant. Also called 'Baiting'.

Spike

A 'spike' is when a player slams the disc down in celebration after scoring, usually a very important point. This behavior is typically frowned upon by purists as it can warp the shape of the disc making it wobble in the air.

Steve

A British term for any point scored when the stationary and marked receiver is thrown the disc after his marker/s run away from him. A shrug before catching the disc makes it a 'Full Steve'.

Strike

A call made by a teammate (who is usually on the sideline) telling the mark to switch the force momentarily, thus cutting off a possible force-side throw.

Swill

A throw that can only be completed with an amazing effort by the intended receiver. Often used to describe hospital throws or throws that lack sufficient spin, causing the disc to fly without stability through the air.

Swing

A throw from one side of the field to the other. This type of throw does not in itself have the purpose of getting closer to the endzone line, but of shifting the focus of play to the other side of the field or of resetting the stall count.

Taco

A disc that has become warped due to a foot block, a player stepping on it, or a throw that nosedives into the ground. Generally a tacoed disc is either straightened by the next handler or is removed from play and repaired on the sideline.

Turf

To throw the disc so that it hits the ground shortly after being released, usually a result of poor execution by the thrower.

Turn

Short for turnover. Said aloud so all players on the field can recognize the change of possession.

Universe Point

When each team only needs one more point to win the game, this point is called 'universe point.'

Up

Yelled by the defence when the disc is thrown by the offence to alert the other defensive players.
