Dude, Seriously, Stop That.

On my flight to Pittsburgh, I sat next some forty-something guy who would eat his peanuts in the most annoying way possible. He'd pour a couple into his hand (which is fine), then he'd do this thing I'd never seen anyone do: he jiggled the peanuts around in his hand, using a motion not unlike the one we use to symbolize jerking off, cocked his head back so it was perpendicular to the rest of his body, and slammed the peanuts violently into his mouth. It took seven of these action sets to finish off the tiny bag of peanuts they gave him (yes, I counted). So...irritating.
