usually a mix of retard and tird, often used online as an insult
player1: OMFG HOW THE HELL DID U MISS HIM, NOOB!!!
player2: stfu, like ur any better, retird
Retird is a really retarded way to spell retard. People who spell retard in this way should be called RETIRDS!
In the future, retarded people will be offended if someone mistakes them for a retird.
Samira: Rikard! You are such a retird!
Richard: That's "retard" Samira. Learn how to spell...
Samira: Shudddduppp! :)
