Fat Midget Nickname

Alright listen up, dummy. The joke is that "Jigglypuff" sounds like "jiggly puff". So, someone who is a fat midget might be called that because they jiggle when they move. This is funny cause you expect a serious answer, but instead, you get a goofy Pokemon name. I bet you still don't get it and you are googling now what "jiggly" means, ha!
