A word used to describe someone who lets out a secret or promise, breaking the persons trust during the process.
(this word was used against my brother from my
8 year old sister, when my brother
snooped in her
diary and let out one of her secrets during dinner).
Alessio: "Sometimes I pretend to
sleep on the couch..."
Sienna: Why'd you read it? You're such a
teller-about!
Alessio: *laughs*
