Snuggie Surprise

This occours when you are wearing a Snuggie and you pass gas. The snuggie material traps the gas ,sometimes for hours, until you get up and are surprised by the smell emitted.

While doing it snuggie style, the receiving end accidentally drops a "surprise", causing the upper half to scream and cry about shit leaking everywhere. Although the snuggie is warm, the warmth of feces is never warranted; therefore, it is always a "surprise".
