The act of punching a girl in the nose and then following up with ejaculating in her mouth. It is so called due to the British Royal Navy's sinking of a German battleship, the Bismarck, in May 1941. Once the ship sank the British sailed round gunning the floating survivors thus leaving a trail of bloody seamen, or "bloody semen".
Hey, I gave her a Bismarck last night she won't forget in a hurry.
