A combination of the words "fucking" and "retard". Used to express anger towards someone other than yourself. Instead of wasting your valuable time screaming, "YOU FUCKING RETARD!!! I CAN'T BELIEVE YOU DID THAT!"
You can just say....
"YOU FUCKTARD!!! I CAN'T BELIEVE YOU DID THAT!"
See the excellent reasoning? :)
Your friendswill be impressed.
A person for whom the word retard is too good. This word is reserved for people who do or say things that even the most retarded of retards wouldn't do
