What does "Burn One" mean?
Definition: The phrase to 'burn one' means to smoke some weed, usually meaning to smoke only one joint or one bowl. You might be most tempted to 'burn one' during a lunch break at work, or during an intermission at a theater. It's almost always a very quick smoke session, so you can get right back to whatever you were doing beforehand — even if it's just sitting on your couch. You can also say you're going to 'burn one down' — if you're not with a bunch of narcs, they will probably know you're talking about weed and not your neighbor's house.
