look up any word, like ratchet:
To continually punch one's friends in the arm and they respond back until they either give up or some mature fag asks you to stop it.
Steve: lets have a Jippo-war
John: no thanks man, ive just had an injection

Steve: *hits john in arm*
John: damn stop it. its that fag from yesterday that said he would hit us both if we did this
