When your a dirty little masturbating gremlin. Most weed wankers dont have jobs, are on the benefit and are spending that money on toilet paper, porn mags and the finest kush. They wank off either during or straight after smoking some sticky icky but in any case. Perverted.
Your being arrested for being a freaking weed wanker sir. You are a tosser and are going to jail to be raped.
Usually when someone is working very hard or when they tell a terrible joke and your being sarcastic that their joke is good
