When you're so high and you're doing the deed and then you pass out like a total loser. It's called 'Jack Blacking it' or 'Knocking Off'.

I tried to 'Jack Black it' last night and ended up on the floor like a total mess.

He 'Jack Blacked it' at the party and fell over like a drunk hippo.

I 'Knocked Off' after doing it while high and ended up in the hospital.
