A word that is used to describe stupid or mentally slow people, that openly makes fun of people with disabilities, especially metal ones. There are a lot of words for stupid, and if you can't find another one, maybe you're the one who is stupid.
Person 1: Person 3, stop being so retarded
Person 2: Please don't say that, it's harmful to the disabled community.
Person 1: Oh, sorry, I didn't know the history behind that word, thank you so much for educating me on that, allow me to rephrase, "Person 3, you need to stop being so freaking stupid all the time! Like, do you think any of your actions through? Did braincells ever develop in that thick skull of yours? You just came out of the womb crying and you never stopped, and your actions are impacting others in a harmful way! You need to accept critisism with grace and humility and stop acting like you are the goddamn king of your sh*tty highschool! No one likes being around you and no one misses you when you're gone, because you refuse to learn anything. You are white and you still say the N-word even though people have tried to educate you on why it's unacceptable for you to say that. And I bet that you laughed at Person 2 over here when she corrected me on my incorrect vocabulary, as if you would miss the r-word, as if it is so incredibly vital to your vocabulary that you simply would perish without it. Get your wet-breadstick ass over to the beer because apparently getting drunk at parties is your only talent, you stubborn, soup-stealing, hollow husk of self-pity and disregard for others of a loser"
