blabberjockey 

Someone you would tell a secret or rumor to if you wanted it to be spread around. An individual who tells everything he or she knows to everyone. A blabber mouth gossip who is compelled to tell all without discretion or consideration for any ramifications.

I told her my feet hurt. Now everyone is giving me home-remedies for gout. She's quite the blabberjockey.

Blabberwocky 

A loquacious drunk prone to telling long nonsensical stories while gesticulating furiously.

Last night I saw a blabberwocky get ejected from the bar for knocking over a servers tray of drinks while trying to tell a story about flyfishing.
