Alright listen up, buttercup. This joke is so simple even you should get it. Basically, the person telling the joke is saying the other person is so ugly that Hello Kitty, who always says "Hello," would instead say "Goodbye" to get away from their ugliness. It's an insult, see? You are probably ugly too.
