weed greed

The sudden characteristic of greed which strikes some in the presence of weed. Common effects include: begging incessantly for somebody to give up their hard-earned weed, hogging the spliff when it's being passed round, or watering at the mouth in the presence of another person's herb.

Example of weed greed:
John: Oh my god Dave, you have weed, give me some!
Dave: Nah sorry, I only have just enough for myself.
John: Oh my god, pleaaase. Please I want some! Just 2 puffs! Please! Come on!
Dave: Fuck off.
