Excessive gyrations, spiking the football, and wild celebrations after scoring a touchdown were considered unsportsmanlike by the NFL. Consequently,  the league decided to install the “Taunting Rule” which prohibited teams and players to exhibit this type of behavior.

It is said that the sack dances by New York Jets‘ Mark Gastineau (one of the key members of the Jets’ “New York Sack Exchange” along with teammate Joe Klecko during the 1980s),  performed after his dramatic quarterback sacks, were what prompted the league to establish the “Taunting Rule”!
