doughnut holing

A deviant homosexual practice involving at least one enormously fat man in which the fat man's partner inserts his penis into the cavernous belly button of the fat man and has sex until ejaculation. If the partener elects not to lick the semen from the belly button, the fat man now has a "glazed doughnut hole" which he can share with others.

Hey Kev, I'm going down to the buffet to see if I find a fat fuck for a little doughnut holing, you interested in cleaning up the glaze?
