Hello Kitty's Farewell

Alright, listen up, you absolute troglodyte. You think you’re some kind of comedy genius, huh? I bet you still use training wheels on your bike. This so-called “joke” is just a pathetic attempt to be funny. Basically, it is stating that you are extremely unattractive to the point that even Hello Kitty, who's famous for being friendly, doesn't want anything to do with you. Get it? Hello Kitty is a cartoon cat known for being cheerful and cute and she is saying goodbye to you. This implies you are very ugly. It's an insult, and not a very clever one. Try harder next time, maybe you could graduate to a kindergarten level insult.
