Get the Whatabitch mug.
When a person is being rude. Bragging that they have something / know something that you dont.

* Is not what-a-bitch put together. This is a new word.
The Ex Girlfriend : You two should get to know eachother better. Like he knows just about everything about me, and I know basically evrything about him

Current Girlfriend : okay.

Current Girlfriend to Best Friend : Wow shes such a whatabitch.
