CUM U 

A variant of Central Michigan University but spelled like it would be Cum University. Due to incest that takes place in Mount Pleasant, the cum at CMU is most likely going into their cousins. Fuck the chips.

Dude, don't go to CUM U. If you cum in a girl there you're cumming where her cousin cummed.

Went to CUM U and saw two cousins fuckin. I thought I was in alabama.

Cum Up Short 

That annoying scenario when you're wanking to a great porno, a good scene comes on, and decide now is the time to go for it. So you get to the vinegar strokes......only for the scene, at that crucial moment, to cut to a far better, hornier one! Thus missing out on an even more intense knee-trembler.

It's one of life's great disappointments.

Dammit Ivan, I was having a great wank last night, only to fucking cum up short! What a jip.
