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
