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.
