A Greb is the alternative, in the UK, to a Goth, only slightly more active in the sense that they like the new age punk and metal music and dress more modern instead of pale vampires. Grebs are mostly recognised for peircings, long hair, hoodies and black clothing with spikes and chanins.
1. Hey man, you're such a greb.

2. Dude, did you see Tom and that grebby dude over there? ewww!
