the sliding of one's whole hand into another's anus
Not only the name of a seriously kinky sexual act, anal fisting is also a gamed to be played in extremely public areas. Taken from the idea of ‘bogeys’ and originating from Ryton rugby club the object of the game is to shout anal fisting as loud as possible in the most public place trying to get as much attention of possible. The way to win the game is to out shout your opponent so that they give up as they feel it is getting to embarrassing.
