Gnar Kill 

A really, really ugly girl. So disgusting that even if you were drunk/high/lonely you wouldn't get with her.

Dude that girl at the club was so gnar kill. Not even the hobo with one leg would get with her.

gnar kill 

a play upon an old surfer term gnarly, meaning "passion-kill"...Originally from the Greek Gnarkillicus , meaning "he who commands no passion".

The first set of waves was so gnarly , but the barracuda that bit my cod was a total gnar-kill , dude!
