You spontaneously combust into nothing. By using your own whole body, which the spell consumes, you can use this reaction whenever you are listening to a conversation you don't like, trying to get out of debt, or however you like.

(This is a joke spell. Use with caution and don't use this in a serious campaign.. or do. I'll just let you decide on how to use this because this spell will kill you no matter what. This spell can be counter spelled, but can't be dispelled. And no, it's not a curse!)
