The munchies

I haven't got any sweeties in the house. It's not even as if I'm hungry, I've already had my dinner and there's the materials to make some more if I wanted. But I have a particular craving for those rocky road bites they sell at Tesco, and I might have to venture out into the night just to buy a snack. Does that make me some kind of stereotypical American-TV drug addict?

Also, why isn't "the munchies" a thing for British-TV drug addicts? I feel like there could be some kind of universal truth revealed if I unravelled the answer to that mystery, but maybe that's just the drugs talking...
