snickelfritz, mid, dirt, brick weed, and midget are some of the main terms me and my friends use to describe lower quality bud.
I'm a proud Canadian and all I've heard is 'shwag" and "bunk". It's been year since I've smoked pot, but I could wager that those terms stand today.
Schwag appears to be the most universal term. Sometimes we call lower quality weed shake even if it isn't really shake. Another term I used to hear is commercial, as in commercial-grade pot. I never called pot Mexican unless it actually came from Mexico, some good quality stuff comes from Mexico but on average it doesn't compare well to stuff from Colombia, Jamaica, etc. Mexico seems more interested in quantity than quality of its herb.
haha same here. skunk is good where i come from. i call bad weed dirt, shank, downtown brown, shitweed...etc lol i cant remember the last time i had bad weed to be honest. lots of good good around here
my bad, looked it up. I don't know how I came across that term for meaning bad. Certainly wouldn't ever consider using skunk for meaning great though.. ha
