Poo ninja 

The stealthy little bastard that haphazardly leaves brown marks on your undies. Also acts as a scapegoat to take the blame for unexplained events for which you would normally be blamed.

Also known as the pantie assassin (for girls :-p )

Damn - the poo ninja's dealt to my tighty whities!

Dad: "Where'd all the change from my jeans' pocket go?"
Son: "poo ninja must have got it."
