Stupid gibberish talk, dumb-ass chatter, talking for the sake of talking even if they have nothing to say or anything productive to add to the conversation. Babbling idiots will also talk to themselves if no one else is around or if they are being ignored.
Our new person is a babbling idiot, she talks like she has just won the word lottery. She has nothing to say and seldom makes sense BUT JUST HAS TO KEEP ON FUCKING TALKING!!!
