These are celebration acts that are now deemed "innapropriate" by the NFL:
Rule 9-2-1-a-1-a
Unsportsmanlike acts.
--Imitating a slash of the throat;
--Resembling the firing of a weapon;
--Bowing at the waist;
--Punching one’s own chest excessively;
--Crossing one’s arms in front of the chest;
--Placing one’s hand by the ear as if to indicate that the player cannot hear the spectators;
--Diving into the end zone when unchallenged by an opponent;
--Entering the end zone with an unnatural stride (e.g., high stepping);
--Going significantly beyond the end line to interact with spectators;
--Standing over a prone player in a taunting manner;
--Attempting to make the ball spin as it were a top;
--Performing a choreographed act with a teammate(s) (e.g., pretending to take a photo, falling down in unison); and
--Entering the field of play by coaches or substitutes in protest of officials’ calls.”
Some of these are ridiculous...no High stepping? No ball spinning? Bowing?
