An overused insult, often used by some twat on the
internet (mostly americans). It's pretty
cringe to do so unironically.
Ironic use for comedic effect is ok however, because people who get upset over words over context are
fucking pathetic.
Example 1: "And you actually believe that? You're a
fucking Autist/Retard!"
Example
2: "Hey, Bro. *Chuckles* Do you see that kid with the Fedora over there?"
"Yea, what about them?"
"He's an autist..."
"How do you know?"
"Have you seen most of the other from my school for kids with
autism? They all were Fedoras!"
"HAHAHA! TRUE!"
