A name for a fuckhead at school. Also, you can use retarded instead. Never tell your teacher that they are a retard or call them retarded, you will get in sooo much trouble.
Retardation Is downloading an app called Musically AKA Tik-Tok and doing autistic dance moves that people think are cool, but in all reality you're being made fun of.
I developed retardation when i started using Musically/Tik-Tok.
someone who thinks that a PC's performance relies on an SD card commonly gets provinces mixed up with cities in the United States of America and has no ability to sitstill for more than 3 seconds. Name usually starts with an R standing for retard.
Person 1: Hey look at that retard being annoying while people are trying to teach him to use a spreadsheet
Person 2: Yeah fuck him.
