Someone pushes someone they don't like so far that they eventually start to get violent. However, this doesn't quite work when it comes to smarter people and pacifists, or maybe Bob just can't be bothered with the pushing process to begin with. That's when this trope comes into play; Bob purposedly hurts himself just to get to Alice. Whenever Alice tries to explain that Bob did this to himself, nobody believes her because "Why would someone do that?"
Technically, this can range to Bob destroying his own possesions too, as long as it is just to get Alice in trouble (As opposed to just acting in a fit of rage)
