A super sized booty, like some old school McDonalds super size booty. Similar to the McDouble where in between two buns is two stacks of delicious meat. Bonus points if the persons name begins with the prefix "Mc". ex. McKay

McBooty 

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!

Moody McBooty

A person, typically a female, who seems to be aggravated by all the things you do, when in actuality she cherishes those flaws but refuses to show enthusiasm. She also has a nice butt, hence the "McBooty"

OMG, if Emily wasn't such a Moody McBooty, maybe I wouldn't be so horny and want to kill myself at the same time!
