The pre-drinking before heading out to a bar, or other event where overpriced liquor is the norm. "Pre-flight" enables said users to get liquored up before the event - so as not to spend as much money later on at the bar. Term used mainly by Marines, but other military types as well.

Get the pre flightmug. A mandatory shit you take at the airport, before boarding the plane. Because you don't wanna drop a load in those cramped nasty-ass airplane bathrooms!
Hey Steve, I just took my required pre-flight shit. No way in hell I'm using the bathroom on the plane to drop my load!

Get the pre-flight shitmug. A quick inspection of essential items (Phone, Wallet, Keys, Ipod..) before leaving the bar slightly inebriated.
