McBooty is the sexual act of buying a Big Mac from McDonalds. Then, while having a female or male ride on your penis. You pull apart the buns and press them against the butt cheeks of the female or male. Then, before ejaculating, ejaculate into the burger and make them eat it.
Man 1: Dude! Last night my girl finally tried the McBooty.
Man 2: How did she like it?
Man 1: She loved it!
