vagberries 

A word used to trick someone into thinking you are going to tell them a secret, when in reality you replace the secret with this vulgar phrase.

Comes from greek root- Vagina: definition- unknown.

Kaitlin: Wanna hear a cool secret?

Evan: Huh??!?
Kaitlin: Jokes on you! Cool magic huh?
