Worst insult said about you?

What's the worse thing anyone has every said about you? And how did you respond?

Once in high school two guys sitting by me were grading the girls in the school based in how hot or fuck able they were... my one friend got a 6 and they gave me a 2, which was the lowest number they gave when I was listening... it kind of bothered me for a while... now I laugh because those guys? I wouldn't even give them the time of day now and I get asked out on a daily basis.
