Someone who won't shut up.

Chatty Cathy's self important brother.

Interchangeable with Chatty Cathy, but sometimes also implying someone who talks over people, even when the other person has something more relevant to say.
Hey Chatty Charlie, just because you won't stop talking doesn't mean we haven't figured out you've got nothing to say!
