The Online Insult Disease (TOID)

(TOID sounds funny.) The overuse of insults you commonly see on YouTube comment sections, or arguments on Facebook. Such words as fag, bitch, pussy, queer, ho, (sometimes) nigga, lame-ass, dumb ass, dick, and a ton of others can probably be named, but there's too many, because people have such an amazing vocabulary, even though most of them spell like kindergartners. Also, when faced with a good comeback, they either:
1. Say the exact same words they used again.
2. Say stupid, having nothing else to say.
OR
3. Close the browser window, obviously feeling defeated.
