When the teacher asked the child who was president before Barack Obama, she answered, "Bunnypants," because that's what her parents had always called him.

To have a piece of matter attached to your rear (to your pants usually) by having sat on something, or simply your own stupidity so as to facilitate a 'rabbit tail' on your pants.
