U Dumb Fuck. Usually pronouced kinda like (youdeaf), and is usually played by a joke by sayin UDF to another friend, making him think that you said something about him being deaf.
"I got the answer wrong" "Youdeaf?" "No i can hear" "No, youdeaf?" "I can hear man!" "UDF, u dumb fuck!"

A poorly run company that attempts to be cool by using the same tired old puns in their advertising campaigns. Also a terrible choice for employment as all employees are treated like thieves and morons. Also known as United Dairy Farmers.
I worked at UDF until I realised everyone in charge is a dipshit.
