Grump Bump 

When a certain YouTube video suddenly get a lot of views as a result of being referenced on GameGrumps.

This comes from the YouTube show, GameGrumps. It was created by Dan during Part 14 of their Legend of Zelda: Wind Waker HD series.

That Monty Python skit got a Grump Bump when Arin and Dan acted it out.

Grumper 

An especially hot and steamy shit. Grumpers often leave you very sweaty and exhausted. They're mostly taken under less than ideal situations like port-o-johns and bar bathrooms.

Man I was tailgating on Saturday and I had to shit some fierce. I went to the port-o-John and dropped a fiery grumper. My asshole was never the same.

Lap Double Grump 

Where 2 individuals, most likely 2 men, engage in simultaneous pooping whilst on the laps of each other. The partner on top finds a small gap between the bottom partner’s legs. This has only been pulled off a handful of times in recorded history.

My boyski we only have one toilet, might have to pull off the Lap Double Grump
