When a girl blabs too much to other random people, about a personalconversation or something you confided in them. A big mouth. A rat. Usually named Brittany.
Can you believe Brittany told everyonewhat I said? What a blabbany. I can't trust her with anything.
I hate how I tell her stuff and she goes off in her luluroe crap and spreads it around to all her co-workers. Frickin' blabbany.
