Jeffy 

Originated as a colloquialism long long ago, reaffirmed and popularized through references such as the movie Corker with Johhny Knoxville, 'Jeffy' is a literal substitution for retarded.

I need you to buy me a trenchcoat while you are in Russia. In regards to style, you have keen eye for stuff that doesn't look Jeffy right?

What? You want me to work on my wedding day?! That's absolutely fucking Jeffy, dude.

Psst, listen to what I call that kid with Down's Syndrome over there.
"Hey Jeffy!"
He just smiled at me...

Man, you gotta quit drinking; you're acting Jeffy and I'm gonna kick your ass if you keep it up.

Jeffy 

Jeffy is a very sexy puppet with nice fashion sense with clothing saying

"Jeffy" and having a hand up his butthole. Jeffy likes to become a robot for no apparent reason and shoot laser beams at his father Mario. He also may have anger issues and slight bipolar problems because of the fact that his now dead father fed him green beans everyday for every meal. One day after inhaling his Skecher fumes he suddenly raged and killed his beloved Mario green bean lover. Jeffy is now kidnapped and being raped by Aretta (Thunderthigh29's ex)

I heard Jeffy the hawt bad boy of the school killed his loving green bean loving father Mario!
