look up any word, like hipster:
 
1.
A confidon't is the name you give to that friend of yours who just can not keep a secret. They can't help themselves. They will tell at least one person.

The opposite of a confidant.
Someone you can't completely trust with a secret.
Someone who will tell your private business to others, either on purpose or by accident.
He is a confiDON'T, my friend. Don't trust him with anything you don't want to see on Facebook! Damn, he will tell everyone!

She promised she wouldn't tell anyone, but she got hella messed up and told like ten people...confidon't! Never again. Do not tell her anything.
