The blackout express can be described as a roller coaster of sorts but one upon which you get on voluntarily. You usually hop on after a shitty shitty day. It usually starts off slow, shotgunning beers with your bros on a tues afternoon or having margaritas with your bitches. Then like every roller coaster, it reaches the top and goes straight fucking down hill from there as you think you handle ten shots in ten minutes and proceed to creep on some girl/sleep with some nasty dude, get in a fight, boot, rally, piss in the middle of the street, boot again, and then finally pass on the floor and get penises drawn on you. Cheers.
Mac: I failed my finance prelim, heres to a good night! (while holding a shot of bartons) I'm hopping on the blackout express!
Tyghe: For fucks sake dude its 9 AM on a monday.
Mac: Sorry for partying?
Tyghe: Welll.....fuck! Give me a shot.

When one eats a whole pizza pie and does not recall eating the last slice. S/he then blames another for jacking the last slice.
"Did one you just eat my last slice of pizza?"
"I just saw you eat it; you must have had a pizza blackout."

An African that mutes people for the simplest thing in a discord server called “waterfall”. Autistic as hell. And changes his profile pic to anything anime related every 24 hours.

A drinking game developed by the Beta Sig fraternity and most commonly played by McGill Management students. "Blackout train" is a ten minute track that an audience with, beer in hand, listens to and must drink every time the song changes or the track says "Blackout train." Depending on how quickly one drinks his/her beer, this results in a minimum of two full beers being consumed in under ten minutes, usually more as the beer is often communal and people want to get as much as possible. This game is often played as the group is leaving for a new location, as to start the 'blackout train' of people: a procession of people down St. Laurent who will not remember what happened post-Blackout train.
