a green sticky form of diarrhea that drips out and gets stuck in your ass hair. Then quickly dries forming a crust that you wont know about until tomorrow morning when you get in the shower
When I went to take a dump I wiped my ass but nothing was there later I found all the crusty gax in my new leopard print silk boxer.

A term for when you're unsure if some one is gay.
I wonder if he's gax?
