D.F.F. 

designated fat friend.
In any group of girls, there usually a couple of hot ones and a token ugly and/or overweight girl, the D.F.F., who supposedly has the best "personality".

Last night the boyz and me went to the bar and met 4 girls. Tony, Mike, and Rob went home with the 3 hot ones and I got stuck with the fucking D.F.F. Man did I take one for the team!

D.F.F. 

D.F.F. is an acronym meaning “Down for fucking” it is commonly used by immature boys who have small dicks and only want women for their bodies. It is a very easy way to get blocked.

Girl: Hey i think i like you

Boy: I like you and wtv but D.F.F.?
Girl: Uhm no?
Boy: *Blocked*

D.F.F

Acronym for "Designated Fat Friend"

the D.F.F. is the friend attractive girls bring with them, because the D.F.F. is unattractive, so in terms of relativity (see even hot chicks use einstein) the hot chick looks even hotter.

the D.F.F. tends to believe that if they are hanging out with beautiful people they must also be beautiful. what is important here, is that they are wrong.

the D.F.F. is historically the person with who the "wingman" must "take one for the team"

You: Oh man that chick is fuckin smokin
wingman: hellz yeah son
You: I'm gonna go talk to her, oh wait, she has a D.F.F.
wingman: FUCK
