This word describes me perfectly but all jokes aside this word generally means stupid, dumb, unintelligent etc. It's also used as an insult. A very popular one might I add.
Are you retarded? Geez is that guy actually retarded? You're retarded.
when you've been tarded before, and are tarded again
I never thought after I was tarded once, that I'd be retarded again and again
An insult used by smooth-brained individuals who can’t think of anything creative to say.
