marshmallow scooter 

When a man ejaculates on a woman's face while on top of her, then sits on her face and scoots forward, so as to smear his ejaculate all over his gooch and buttcrack.

Dude, don't go anywhere near Victoria. I heard Greg gave her a marshmallow scooter.

Homestar: "Before I drink a tall glass of melonade, I like to eat about 147 FLUSHY PUSH MARSHMELLOWS! Seriously folks..."
Director: "Cut! You said Flushy Push."
Homestar: "I know! Can you believe it?!?!"
Director: "They're called Fluffy Puff."
Homestar: "I know! Can you believe it?!?!"

"Before I drink something, often times I eat something too!"

"Before I drink a tall slice or marmalade I eat 147 marshmellows. I mean fluffy puffies."

"They're fluffity! They're puffity! 12345!"

Roast a marshmallow 

Slang for smoking a cigarette or joint.
Roast because of the fire you need to light it and marshmallow because of the white paper of the cigarette or joint.

Let's go roast a marshmallow.

Me and Rocky roasted a couple marshmallows last night.

Slippery Marshmallow 

A slippery marshmallow is when you accidentally drop the entire roll of toilet paper into the toilet while trying to wipe your ass.
