Pussified NFL.
LOL, that’s funny!
The gesture essentially started out as a “smelling the fingers after fingering a vagina” and predates any football moves by at least a decade. Players started doing it as a show of disrespect (I’ll allow you capable people to connect the dots).
It’s not a violent gesture, but in our puritanical culture where extreme violence is less offensive than a nipple…well, there you go.
