phantom farter 

Some body who lays a silent but grossley smelly fart and walks off like nothing ever happened..

There twenty people on a bus. One guy passes that stink goul fart very quietly with nobody the wiser and gets off at the next stop. Ten seconds after he's gone, everybody wants to know who farted. Somebody shouts "phantom farter stikes again"
