Ballsweiner
A word used as a vulgarity substitute, when conditions don't allow for a word such as "nutsack" or "dick". Also, is mildly entertaining to bystandards with a good sense of humor when said loudly in an exclamatory fashion, similar to the way a vendor at a sports game would say "cold beer".
My aunt and uncle were in the room when i stubbed my toe, so instead of screaming "fuck", i shouted, "Ballsweiner!"
