When someone has sniffed far too much ketamine
the night before and now feels delirious, tired and vulnerable. This is similar to a comedown
from a night taking ecstasy, but has different effects. This term originates from Nottingham
where the ketamine scene is very big.
"Fucking hell Gregg you look rough", "Yeah mate, I had 6 lines of wonk last night and Im on a right ketdown"
