Get the belgian burnmug. A sexual act in which a female partner partakes in coitus with a male partner, usually her cheating ex. When the man is about to ejaculate, the woman pulls him out, takes a preheated waffle iron, and slams the erect penis shut between both sides, thereby providing the conclusive burn and eliminating any future relationship endeavors.
Guy #1: Why are you walking like a butthurt penguin?
Guy #2: Chloe wanted to take me back, so she invited me last night and just when I was about to come, she gave me a fucking Belgian Burn!
Guy #1: What a bitch.
Guy #2: The doctors say the bandages can come off in a few months.
Guy #1: Anything else?
Guy #2: ... I still have trouble peeing.
Guy #1: Okay.
