Boom Hull Shot
The phrase "Boom Hull Shot" is yelled by EVE players when they've successfully damaged an enemy ship enough to reach its Hull, the last line of defense that is paper thin on a ship.
EVE Pirate: "I'm almost finished with his armor, now the hull!"

*EVE-Miner takes 2300 damage, destroying the ship*

EVE Pirate: "BOOM HULL SHOT!"
