The act of filling a female's three holes with some steamy hot man meat, such that she becomes watertight and thus seaworthy.
Jenny became seaworthy when she went to that UO football party last weekend. I heard that three guys parked their pink buses in her fur garages at once. Bitch became more seaworthy than the fucking Titanic that night.
