The D. F. F. is the girl in the group who is always getting laughed at because she’s too big and not hot. She thinks she’s cool, but she’s just the background joke.
"I’m not fat, I’m just a D. F. F. for my friends."
My D. F. F. ate the whole pizza and still said she was fine.
The D. F. F. tried to take a selfie and it was just a blur of cheese and face.
