Grundles 

Grundles are brown cave-dwelling creatures from the My Little Pony movie. They look like monsters to most people, but, as they constantly reassure Baby Licketysplit and Spike the dragon, "Grundles good!" They are helpful, friendly creatures. Interestingly, Danny DeVito played the Grundle Leader in the movie.

Grundles not monsters! Grundles good!

Grundles is actually short for grundlemires, as panties is short for underpants.

If you cut somebody off in traffic and they start flipping you off or shouting obscenities, simply say "Hey, don't get your grundles in a bundle, pal."

Grindlesnatch 

An utter Abomination. The foulest of all creatures known or unknown to mankind, often the "cute friend" a girl tries to set you up with. Has the comparable sexual attraction to a menstrating Jaba the Hutt. Typically large enough to contract her own gravitational pull, with the blubber capacity to be used as a flotation device in dire circumstances. See Titanic. The equivalent of a "0" on a 1-10 rating scale, assuming negative numbers are not allowed.

"I would rather face fuck a pitbull than kiss that Grindlesnatch."
"I found myself being drawn to her physically. Literally. In a bad fucking way."
