Multi-flasking 

A phenomena in which everyone on the ski lift has a flask of booze and shares it with the rest of the chair.

G: Dude, why is your bloody leg bone sticking out of your ski pants like that?
B: No idea dude, it might have been the multi-flasking I indulged in prior to the bunny hill.
