look up any word, like blumpkin:
Suggesting this is a way of saying someone is talking or acting crazy. Used to express disbelief, skepticism, or simple mocking. Indicates a level of ridicule serious enough to move the subject away from what the other person has said, and onto the state of mind of the speaker.
