means the same as the word retard but makes you sound stupid saying it. (From the movie The Hangover)
Someone says something stupid, and you reply with you are a ratard.

A somewhat derogatory adjective.I invented the word ratard in 2005.It is a combination of retard and rat-like qualities. It can refer to a person or a thing/object.In our house sometimes instead of saying something is a ratard we just say "Voo Voo!" in a stupid voice.
"He's a real ratard!" Or "I made a ratard soup of old left-overs" Or "That used car I just bought turned out to be a ratard"
