McStand

The act of hovering above a toilet while taking a mook to achieve ultimate domage while explosively cleansing your anus. The scarier the mook the better the McStand.

Chuck: "I took a fat McStandy earlier. Almost fell off the toilet I got so domed."

Sausage Egg McStuffin

Also see happy meal.

Whilst receiving deep-throat fellatio from a woman, one may stuff one's ballsack into the woman's mouth at the same time, the sheer volume of which causes her lips and cheeks to stretch wide open (as though she's making a big happy smile, hence it is sometimes referred to as a happy meal.)

Man, look at the mouf on that chick... I'll bet she'd love a nice Sausage Egg McStuffin for breakfast.

When you get sodomized at McDonald's

I wouldn't go to that McDonald's because I always encounter McSodomy there.

MCST

The single weirdest school in New Jersey. VPA kids are insane. Health care kids are all Asians and Indians. Digital design kids are weird. Racist epithets are screamed with affection and Jewish kids are anti-Semites. There are 5 black kids in the school, but everyone has a fake black friend. Teachers either act like your friend or act like they wish they weren't there. You wait for the winter to play in the giant snow pile outside of building 3. You can go to the Deli whenever you want, as long as you bring enough food back for a teacher. There are 6 buildings but building 1, 2 and 6 are the same building and no one has ever been in building 5.

Dude, that kid is so weird, where does he go to school?
