Eating mass amounts of Ecstasy, and fucking random dudes.
I was kimming so hard last night.
(v) To hit on a girl your friend is already trying to pick up, by getting into a one-on-one / deep and meaningful conversation.
We were flirting and then Reece started kimming her! Totally cock-blocked!
Or: Hey Luke, Reece has been kimming the girl that you've been tapping all week.
