mongolian ass eater

A meme that was based off of a tweet that @kaegann made about having a very large spider on his neck, that became widely known on tumblr.

The term is used to describe an unusually large, and creepy-looking bug that may or may not be able to kill you, and may or may not inspire you to burn down your house.

- The actual start of the term -

onlyblackgirl: what the fuck is that
sayayedarbi: It's either a spider or a crab
malik-sad: It’s a Mongolian Ass Eater, it’s a very dangerous and deadly bug, he should thank God he survived that encounter.
