Old Horse Fat

British slang for "dick" or "penis," most popularly used in a work email written by an international law firm lawyer Patrick Smith (now fired).
Smith in email: "Dude, 'Carol' (not her real name) wants some of that double penetration action, so let me know when you and the old horse fat are around."
