The worst thing you can say to a fatty. I was thinking about the worst possible thing to say to a ham.  My thinking went thusly: "Fuck you." A strong classic.  The trouble here is that most hams would enjoy being fucked by a shitlord.  It's also a little stale, and on the way out.  It's being replaced with: "Die in a fire."  That's more of a current-day insult.  Very painful, terrible to comtemplate, and particularly applicable to hams since their fat burns so well.  However, I did think of something to one-up even that: "Don't ever change."
