It can mean anything you want it to. But usually means somithing bad, discusting, or gross.
Damn, that chicks vagina was mad grimey.It had the grimiest smell and looked like a bulldog eating mayonaise while watching the grimiest T.V show while somebody is taping with his grimey new camcorder which he got from that grimey store Wal-Mart on a really grimey day in October while wearing a grimey T-shirt and in Wal-Mart he saw a grimey person trying to steal some oranges which were very grimey. (Jake says this fuckin word way to much because he is a very grimey person.Go to hell Jake you grimey dude.)
