Flag Football Glossary
Flag football borrows most of its vocabulary from tackle football, then adds its own — the flag pull that replaces the tackle, the no-run zone, the pass-rush distance. This glossary defines the terms every player, coach, and fan runs into, grouped by theme. The definitions are body-agnostic; where a term is a rule with a specific number, we define it plainly and point you to the full rules for the exact figure. For the roles behind these terms, see positions and plays & formations.
Offense terms
With no blocking and nearly everyone an eligible receiver, offensive terms describe who touches the ball and how it moves. For a fuller look at each role, see positions.
| Term | Definition |
|---|---|
| Quarterback | The first player to gain possession after the snap and the offense's primary distributor — passing, handing off, or pitching the ball behind the line of scrimmage. |
| Snapper (center) | The player who puts the ball in play. Because the snap counts as a backward pass, the snapper can release into a route and becomes an eligible receiver. |
| Eligible receiver | A player allowed to catch a forward pass. Because there is no blocking and no linemen, nearly every offensive player is an eligible receiver. |
| Motion | A receiver moving laterally or backward before the snap — used to change the formation, create leverage, or reveal whether the defense is playing man or zone. |
| Handoff | Physically giving the ball to a teammate behind the line of scrimmage. With no blocking to open holes, handoffs are a base of the running game. |
| Pitch | A short underhand toss to a teammate behind the line of scrimmage, usually used to get the ball to the edge in a hurry. |
| Lateral | A backward or sideways pass. Unlike a forward pass, a lateral is legal from anywhere on the field and can be thrown more than once on a play. |
Defense terms
Defense in flag football is mostly about ending the play and covering the pass — pulling the flag, choosing man or zone, and deciding how many bodies to send at the quarterback.
| Term | Definition |
|---|---|
| Flag pull | Removing a ball carrier's flag to end the play — flag football's equivalent of a tackle. The ball is spotted where the flag was pulled. |
| Deflag | To pull a ball carrier's flag; the term also describes a flag that falls off on its own, which typically ends the play at that spot. |
| Rusher | The designated pass-rusher, who must begin a set distance behind the line of scrimmage before pressuring the passer — the exact distance is set by the rulebook. |
| Blitz | Sending an extra rusher to shorten the quarterback's clock, at the cost of leaving one fewer defender in coverage. |
| Interception | A defender catching a forward pass intended for the offense — a turnover that gives the defense the ball. |
| Man coverage | A scheme in which each defender is assigned one receiver and travels with them wherever they go. |
| Zone coverage | A scheme in which defenders guard areas of the field rather than a specific receiver, keeping the play in front of them. |
| Safety | A scoring play for the defense, typically when a ball carrier is deflagged in their own end zone. The point value is set by the sanctioning body — see the rules. |
Rules & field terms
These terms govern how a down starts, stops, and is penalized. Several are rules whose exact numbers vary by sanctioning body — the Olympic/IFAF game, NFL FLAG, and the college game each set their own — so we define them generically and defer the figures to the rules page.
| Term | Definition |
|---|---|
| Line of scrimmage | The imaginary line, marked by the ball's spot, where each play begins and across which the offense is trying to advance. |
| Down | A single play. Each team gets a set number of downs to reach the next line to gain — the exact count varies by format and is set by the rulebook. |
| No-run zone | An area of the field — commonly just before each end zone and near midfield — where running is prohibited and every play must be a pass. The exact locations are set by the sanctioning body; see the rules page. |
| Dead ball | A ball that is no longer in play, meaning the down is over — play stops on a flag pull, an incompletion, a score, or when the ball carrier steps out of bounds. |
| Spot foul | A penalty enforced from the spot where the foul occurred rather than from the line of scrimmage. |
| Flag guarding | An offensive penalty for using a hand, arm, or the ball to block a defender from reaching the flag — swatting a hand away, covering the flag, or lowering to shield it. |
| Pass-rush distance | The minimum distance a rusher must start behind the line of scrimmage before rushing the passer, meant to keep a wall of defenders off the quarterback — the rules page has the exact yardage. |
Formations & routes terms
The scheme vocabulary — how the offense lines up and where receivers run. These terms come up constantly on the plays & formations page, where each one is shown in context.
| Term | Definition |
|---|---|
| Spread / empty | A formation with receivers split wide and the quarterback alone in the backfield, stretching the defense across the whole field. |
| Trips | Three receivers aligned to the same side, used to overload a zone or isolate the lone backside receiver in a one-on-one matchup. |
| Bunch | Three receivers clustered tightly together so their releases cross, creating natural separation against man coverage. |
| Stack | Two receivers aligned one directly behind the other, giving the back receiver a free release a defender cannot jam. |
| Slant | A quick route that breaks at an angle toward the middle of the field — a staple throw that beats man coverage before pressure arrives. |
| Out | A route that breaks toward the sideline, offering a safe completion against soft or off coverage. |
| Streak / go | A vertical route run straight up the field — the deep, home-run shot that clears a defender or wins a footrace. |
| Mesh | Two receivers running shallow crossing routes that pass close together, springing a receiver open by forcing man defenders through traffic. |
| Pick / rub | When a receiver's path impedes the defender covering a teammate. Incidental crossing is legal, but deliberately screening or picking a defender is a penalty. |
