Ba-dong-a-dong
Ba-dong-a-dong is a new insult that came from the streets. It’s a way to say someone has a small penis, and when you use the plural, you’re saying they have a small penis and also tiny nuts.
My friend said, 'You’re a Ba-dong-a-dong and your pants are too big for you.'
My mom called my brother a Ba-dong-a-dong after he lost a bet.
My neighbor said, 'You’re a Ba-dong-a-dong and I bet you can’t even run a mile.'
