SWO

SWO stands for "smoke weed occasionally" or in some cases "smoke weed often". The term was developed by non-stoners in response to the popularization of the term SWED (smoke weed every day). The ambiguity of claiming to SWO lends it a sense of mystery that SWED lacks.

"Hey man, you SWED?"
"Nah b, but I do SWO."
