Bohemian Shotgun
Right before reaching climax, the male pulls out and furiously slaps the female's vagina. He then proceeds to forcefully re-enter with a single thrust, and ejaculates while shouting "STRILET" (Pronounced stree-let). Which is the Czech word for shoot. Hence, firing the Bohemian Shotgun.
I can't believe you did a Bohemian Shotgun to Owen's mom.
