...what the fuck does it have to do with anything?
Well, since you obviously haven't been following the soccer games: There was a player who bit another player. And we are not talking about a little love bite, it left some bloody toothmarks on his shoulder, naturally the president of his country claimed that the video had been photoshopped and the player had been framed. There was also controversy because he was known to be a biter, this was something that had happened a few times already but he had been allowed to play because the league likes money and not letting a big-name player play might have been counter to that goal.
Anyway, that incident has now been made fun of all over the internet and media and it has even been used in commercials.
