A term originally referring to lousy pot, which has also come to describe anything else lame or inherently sucky.

Low grade marijuana. It'll get you high, but it takes a lot of it. Preferably smoked in blunts and bongloads, shwag should definitely not be the first plan of action. Although, if you're fiending and you've got $5 theres nothing wrong with a nice fatty blunt.

Mediocre Pot.
