It originated from the term "I'll be back in a flash", but with the word "flash" replaced with "flask". It gives a double meaning now, where you can say "I'll be back soon" and also "I'll be back inside an alcohol containing vessel".

Get the National yeet hydro flask daymug. When a man peas in a water flask and then shoves it up his ass. Then he plays the flute really hard and bubbles the piss. The piss drain into his stomach and he throws up everywhere and shits the flask out which covers him in piss and shit. He then mixes all of his poop,piss, and vomit and Diet Coke into the flask and drinks it, causing his stomach to rupture and bleed out and die. You also have to do this in northern Tennessee
