greb stain

A green residue that is left by a greebo. It is usually found on a wall because of its sticky nature. You should never touch a greb stain unless you are a greebo because it could have unforseen consequences.

Person 1 - "Hey, look at that greb stain on the wall."
Person 2 - " go and lick it."
Person 1 - " fuck off, I am not a greebo."

grego

A ghetto, but very cozy. Something you would call a house that is kind of sketchy but still has a homey vibe to it. Can also be thought of as a place to chill with your friends, while still feeling comfortable.

“Have you been to the grego lately?”

“Yeah they got a new couch and it’s super cozy!”
“Yeah sometimes I go there just to take naps.”
