look up any word, like bae:
(1) A foolish or annoying person

(2) A heavy session on the beers punctuated by random journeys across a town on foot or via public transport

(1) "That girl who told us to stop talking loudly on the train was a grine"

(2) "Howay, lets go on a grine on Saturday in North London and see where we end up, bring a couple of tinnies for the train"

A dirty vagina that is loose, smelly, and infected. Someone who has grine is most likely someone who is a slag.
"Oh god, she's got the grine!"
