A once-popular nickname for a certain ex-president, based on a photoshopped picture of him wearing a bunny outfit instead of his Mission Accomplished flight suit.
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.
