What a player yells after getting their ass bombed in the popular 80s boardgame "Battleship."
This was a game with opposing players holding a fleet of ships on a grid. Each turn one player would call out a coordinate to the other player. If there was a hit on a vessel, the player would mark it with a red peg, once the vessel's holes were filled (some had 2, some has as many as 5) the ship was considered destroyed and sunk. This continued unitl one player's fleet was destroyed.
Fun!

The non sequitur, and repeated punchline from a Simpsons episode, though from the normal UD definition for battleship, it could easily mean something vulgar.
