Muffincopter 

When a girl eats a muffin, and you swirl your cock in a helicopter motion while finishing on her face

I gave that chick a muffincopter last night. Some got in her eyes.

Muffcopter

A metaphor used when on the hunt for a female sexual partner.

Dave: Are you hitting the town tonight?
Bob: Yeah, we'll ride the muffcopter!
Dave: Sweeeeeeet!
