The bad buzz you get from marijuana, basically when you get too high. Symptoms include severe anxiety, paranoia, panic attacks, increased heart rate, decreased blood pressure, hunger, dehydration, severe cottonmouth, shallow breathing, nausea, vomiting, loss of common sense, feeling you've lost touch with reality, dizziness and impaired balance and going pale (or "going green"). Not the nicest.

The whole scenario is common amongst first-time users, lightweights and 12-year-old kids. Pure stoners even experience the greens now and again.
"Fucking hell, man, that is some brilliant blow".
"Yeah, just leave me for a minute".
"Fuck, he's going in the fetal position!".
"No, I'm fine, fine, fine!"
"Damn, brother got the greens".

See gay as all hell. Greene references to a male that likes to lick other males unwipe dirty inches. You may also suffer from a tendency to munch on fecal matter whilst jerking-off. Greenes are often recognized by their bad breath and shit-stained teeth. You may want to avoid them at all costs, unless Greenes float your boat.
That guys breath smells like shit, he must have Greened some dude.
