a. Specifically prohibited acts and conduct include:
1. No player, substitute, coach or other person subject to the rules shall use abusive, threatening or obscene language or gestures, or engage in such acts that provoke ill will or are demeaning to an opponent, to game officials or to the image of the game, including but not limited to:
(a) Pointing the finger(s), hand(s), arm(s) or ball at an opponent, or imitating the slashing of the throat.
(b) Taunting, baiting or ridiculing an opponent verbally.
(c) Inciting an opponent or spectators in any other way, such as simulating the firing of a weapon or placing a hand by the ear to request recognition.

(e) An unopposed ball carrier obviously altering stride when approaching the opponent’s goal line or diving into the end zone.
(f) A player removing their helmet after the ball is dead and before they are in the team area (Exceptions: Team, media or injury timeouts; equipment adjustment; through play; between periods; and during a measurement for a first down).
(g) Punching one’s own chest or crossing one’s arms in front of the chest while standing over a prone player.

(k) After the ball is dead, using forcible contact to push or pull an opponent off the pile. (A.R. 9-2-1-XI)
PENALTY—Unsportsmanlike conduct. Live-ball fouls by players: 15 yards [S27]. Live-ball fouls by non-players and all dead-ball fouls: 15 yards from succeeding spot [S7 and S27]. Automatic first down for live-ball and dead-ball fouls by Team B if not in conflict with other rules. Flagrant offenders, if players or substitutes, shall be ejected [S47].
For Team A fouls during free or scrimmage kick plays: Enforcement may be at the previous spot or, if the scrimmage kick crosses the neutral zone, the spot where the subsequent dead ball belongs to Team B (field-goal plays exempted) (Rules 6-1-8 and 6-3-13). For Team B unsportsmanlike conduct fouls during a legal forward pass play (Rules 7-3-12 and 10-2-2-e): Enforcement is at the end of the last run when it ends beyond the neutral zone and there is no change of team possession during the down. If
the pass is incomplete or intercepted, or if there is a change of team possession during the down, the penalty is enforced at the previous spot.
2. After a score or any other play, the player in possession immediately must return the ball to an official or leave it near the dead-ball spot. This prohibits:
(a) Kicking, throwing, spinning or carrying (including off of the field) the ball any distance that requires an official to retrieve it.
(b) Spiking the ball to the ground [Exception: A forward pass to conserve time (Rule 7-3-2-f)].
(c) Throwing the ball high into the air.
(d) Any other unsportsmanlike act or actions that delay the game.
PENALTY—Unsportsmanlike conduct. Dead-ball foul. 15 yards from the succeeding spot [S7 and S27]. Automatic first down for fouls by Team B if not in conflict with other rules. Flagrant offenders, if players or substitutes, shall be ejected [S47].
b. Other prohibited acts include:
1. During the game, coaches, squad members, and authorized attendants in the team area may not be on the field of play or outside the 20-yard lines to protest an officiating decision or to communicate with players or officials without permission from the referee. (Exceptions: Rules 1-2-4-f, 3-3-4-d, 3-3-8-c, and 3-5-1).
