Flash Drunk 

When, from a sober state, you consume a large amount of alcohol (preferably liquor) in a very brief amount of time. By doing so, you go from completely sober to instantaneously drunk, bypassing the 'buzzed' stage of alcohol consumption.

I just got here, the game starts in 20 minutes, and I'm not paying $8 for a beer. Better get flash drunk. Hand me that Jack Daniels.
