Burnover 

The act done by fireman to leave a structure still on fire and the next crew or shift coming in to work to put it out and clean up.

Man, fucking third platoon screwed us good with work first thing this morning with another burnover.

Also occurs when when a wild land fire goes over the top of firefighters.

Burnover 

It's like a hangover but instead of drinking you smoke so much weed you wake up with a headache from dehydration. You could also be stuck with the second day sillies

Dude 1: Hey bro, wanna hang out today?
Dude 2: *sleepy raspy voice* nah man. I smoked so much bud last night I got a burnover. I think I'm just gonna stay in bed and drink water all day.

Bunover 

When you have smoked so much weed, that when you wake up you feel like a zombie. The equivalent to being hungover, but with weed. or the general feeling of smoking too much, passing out, waking up and feeling a little brain dead.

'ahh man im so bunover today, that last joint killed me last night!'
