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."

swindon greb 

A greasy, long haired person who usually listens to screamo, metal and emo. Some times like to seem "in" with the trends so they listen to the "latest" hip hop song 2 months after its video has been relased. Wears dark clothes, normally band shirts. Hates scene kids and chavs. Complains about being labelled and then starts ranting about chavs. Sits on a wall at wyvern theatre and listens to music on their phone. Usually like to get stoned every weekend so they get 20 different people to chip in 50p to a 10 bag and then go and smoke it in queens park. Goes to town every weekend. They think they're badman. They're idea of a night out is to go to furnace night club and listen to local bands who cannot sing so they bree.

swindon greb2: oh em gee yehh i love it
swindon greb1: you going furnace tonight?
swindon greb2: yehhh see you there
