Mayonnaise Biscuit

A mayonnaise biscuit is when an a gay male, during anal sex, cums into the rectum of the other gay male. The male who did the cumming, the proceeds to eat the cum out of the other butt-hole. (Oh and during this entire process Wham's greatest hits is playing in the back ground.) Typically an original Mayonnaise biscuit is done by an older gay male into a Twink but a "Lite Mayonnaise Biscuit" may be fulfilled when said Twink ejaculates into the older males butt-hole and then eats it.

Did you see the smile
On him today?! Robert totally ate a mayonnaise biscuit out of Noah annihilated Twink ass last night!!

Noah came into work all smiles today! Must've convinced Old Man Robert to let him get a "Lite Mayonnaise Biscuit" in last night before Noah was tucked into bed with "warm milk."
