The act of anhilating an object, having an accident with a household item and/or eating serious shit. Essentially, fucking things up hardcore.

Lorna: "I nearly pissed myself when I saw Angie check-minus the coffee table, eat shit on the entertainment center, recieve a beating by the enormous alarm clock and proceed to vomit off of my balcony."
Julie: "Yeah, but it was even sweeter when you check-minused the papason."
