hairy brain - A fancy way to call your junk bag. It’s also called the bald

A fancy way to call your junk bag. It’s also called the bald eagle, the gerbil bag, and sometimes the meat locker. It’s basically your testes’ home.

My hairy brain is the reason I failed algebra.

I told my dad his hairy brain was the size of a donkey’s butt.

My teacher said my hairy brain was so big it could hold a whole class.
