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.

Get the Burnover mug.
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.
