Abridged version of the words "Don't know about that". An exclamation describing someone's subtle disagreement with something said or done; usually when a person is asked an awkward or stupid question.
A:"Dude, we should totally go hang out at the mall today!"
B: "Uh, dunnoboudat, that sounds kinda gay."

Noob: "Hey, can I play some ranked matches with you guys?"
Pros: "Dunnoboudat, you're a freaking noob."
