What is Cubba?
1.
It means an extremely dumb person..beyond dumb acutally. I believe the origin is someone being at such a loss for words that it's a combination of many cuss words.
Whore #1: I'm tired, I've got cramps and my feet hurt. Can I call it a night and go home and lie down?
Pimp: You, you---you's a cubba?
OR
Elle: How was your date with Mr.Sexy
Ella: It sucked...he's such a cubba!
Elle: Oh, yeah...he's from St. Olaf
