Bear Suit 

To get angry all of a sudden, often scaring those around you....

"If you kids don't get your rooms clean, I'll put on the bear suit"

or

"Geez, James really pulled out the bearsuit in that meeting...."

Fish in a Bear Suit 

Originally taken from an episode of the now off-air childrens cartoon, Invader Zim, this phrase can be made into a very disgusting description. A fish in a bear suit is a disgusting hairy vagina.

I went to go down her but that bitch had a fish in a bear suit between her legs. Like damn!

bearsuit 

The pj's that a mans wife or girlfriend wears to bed if she doesn't want to have sex. Like an all flannel outfit or fat pants.

Husband says to him self, " I can see the wife has her bearsuit on again. Looks like more masterbating for me tonight."
