anti-munch 

Origin: contemporary English (my own)

The feeling of lack of appetite immediately following the intake of THC in any form lasting around 20-40 mins subject to the individual.

"Yo man, don't smoke that now cos' we'll get anti-munch...we're about to eat mate!"

anti-munchies 

The opposite of the munchies; When you have no appetite because you haven't got high today. Sucks a lot more when you smoke a lot and suddenly quit smoking or slow down.

Unfortunately there are some people you can't use this as an excuse in front of.

Jon: Yo Adam, wanna hit these funyuns?
Adam: Nah, man, I got the anti-munchies, where the weed at?

Mom: Would you like a nice steak dinner Adam?
Adam: Uh, nah... I already ate at Jon's house

Anti-Munchies 

When you've taken so much coke that you know you won't eat for days.

I did so many lines last night I've got the anti-munchies, I'll never cope with dinner.
