poured milk before cereal, then put ice cubes in it

The act of doing something so horrible, monstrous, and generally bad, that you are doomed to stub your toe and whenever it heals, stub it again.

John: you monster. I hereby doom you to stub your toe-
Jon: That's not so bad.
John:-And whenever it heals, immediately stub it again.
Jon: NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!
