The act of eating heavily out of your fridge in 3 minutes. Usually brought on by cravings
Person 1: Hey man why is your fridge empty?
Person 2: Oh I was power snacking last night.
Being powered through the consumption of illegal substances (snacks) and doing naked pushups late into the night powered directly through snacks!
Me: I hear your interested in teamwork so how about a session of snack powered push ups!
You: That sounds like a great time except for your gonna have to lick my taint first and grab hydration and possibly some sugar free pineapple lube! Stat McNasty!
