[Source] The jizz-box was a musical device. In 13 ABY, the protocol droid C-3PO, who was stranded on the planet of Nim Drovis, auditioned to perform at a cantina called the Wookiee's Codpiece. C-3PO performed by playing back songs stored in his memory core with his vocabulator. The assistant manager of the establishment told the droid that he sounded like a festering jizz-box and rejected him, saying the Codpiece already had a jizz-box to play.
