1. mod. tired; bored. I’m burned out after all that partying.
2. mod. having to do with the ruined veins of an addict. (Drugs.) My veins are burnt out so I shoot in the jug.
3. mod. ruined by marijuana smoking. (see also
burnout.)
What’s left for these burned out kids? 4. mod. no longer affected by a particular drug. (Drugs.) It’s no good. I’m just burned out. The stuff doesn’t affect me at all.
