To fall asleep inadvertently, especially when one intends to do something else (such as to work or study).
I would have been finished with the essay due for my English paper, but I blacked out at 7:30 (PM) and just woke up (it's 11:30 PM). I guess I'll have to pull an all-nighter. I hope I don't black out again this evening.

Guy 1 - "Hey dude, I almost scored with that girl last night"
Guy 2 - "Yeah bro, we could have totally eiffel towered her if you didn't black-out"
Guy 3 - "You're such a pussy"
Guy 2 - "Next time you black-out, don't drop your gay card"
