Proton torpedo

"Polishing the ol' torpedo, sir?"

- Ensign Pavan

Proton torpedoes were one of the two standard guided weapons used throughout the galaxy. Along with concussion missiles, they were popular with just about every spacefaring military throughout history, and were responsible for destroying one out of two operational Death Stars. The secret behind their power, which was considerable, was the "special sauce" which was added to the explosive component; urban legends say that this sauce was also used to season cheeseburgers.

Torpedoes themselves were also something of a metaphor. It was common for junior officers and new soldiers to make penis jokes that involved these weapons, particularly among males.
