babat
Babat is Persian slang for your dad's sagging junk. We use it to tease each other like a silly kid. It's just a friendly way to roast someone without being too mean.
Hey babat, your dad's got a new hobby, he's taking up space in the shower.
Don’t say babat in front of my dad, he’ll be mad.
You called me babat? I’m gonna tell your mom.
