megacannon 

Phallic armament that is typically used by the San Fransisco military to ejaculate their enemies to a cryogenic state. May result in red dragons. Though controversial, many military legends advocate the use of the CODS (Condom Desolator Shield) to displace the hot ejaculate back at the perpetrators. Side effects may include dizziness, scrotumall irritation, and violent backlash from explosive diarrhea

Private: Sir, the enemy took out the megacannon.
General Victor: Quick deploy the CODS and the Peanorg unit!!!
