Mayo Buns is a stunt pulled by a dude in bed. It begins with a man and a woman having anal sex. When the man gets close to 'blowing his load' he pulls out and gets it all over her 'buns'. The buns may then be sticky and/or smelly.
Dude, I got this broad back to my pad and totally gave her a pair of Mayo Buns.
