Someone who has characteristics of defficiency such as a brokenleft elbow, unability to turn hands with palms facing upwards, and thinks like a 6 year old.
Yeah that kid that just got bit in the face by a dog, that's jack campbell the fucking retard.
as seen in rihanna's video "umbrella" a retarded ballerina is one that tip toes around a stage or any similar flat ground and looks as though they are struggling to survive. The tits of the said ballerina are often long and misshapen best seen in the play Cats (not in the video "umbrella")
Shit son! There's that retarded ballerina again, tiptoeing up to the bus stop...let's kick her toes!
