The act of triggering the prolapse of one's partner's anus, either through applying enough pressure on his/her buttcheeks or by simply reaching out to the depths of his/her anus with one's hand and pulling the rectum out while twisting it, in order to lick it and suck it with progressively intense tongue and lip motions, as when performing oral sex. It is important to bear in mind that, after the act is performed, it is conventionally considered a lack of courtesy for the active partner not to return the receiving partner's anus to its original state, usually done by administering an Alabama Whack-a-Mole.
