Where the hell did you grow up? Wait, no, I don't want to hear more about your childhood.Man, this is football. Provocations have existed since the beginning of the game. Provocation is part of the game.
say insults to the ear (a la Materazzi), small kicks to the heels, fingering, squeezing or hitting the nuts with a fast and swift back palm... that has always been acceptable provocation. Players just need to learn not to react to this. Players like Vidal or Medel for example, were always targeted when younger because they used to react in violent ways.
What can't be accepted is violence (whether be fouling or punching/hitting/elbowing, spitting, biting, etc) and cheating on the game.
a finger up your ass (with underwear and shorts) is just funny as feck, and repulsive, but in no way is some sort of violence among men in a football pitch.
Anyway, this is a disgusting behaviour that in no way should be acceptable (even on a personal level, let alone during a game watched by millions around the world, from all ages). Oh and it is worse than biting your opponent.
