Bumucci
To do a Bumucci is to use your arse in an attempt to defend from an opposition player. Doing a Bumucci doesn't really work and the opposition almost always scores. Doing a Bumucci was most famously adopted from the Juve player Leonardo Bonucci who so also happens to be a racist as well as a Milanista.
