The D. F. F. is the friend hot girls bring along so they can look even hotter by comparison. The D. F. F. thinks she’s part of the cool group, but she’s just there to make the others look better.

The D. F. F. tried to flirt with the guy and he looked at her like she was a bad choice.
The D. F. F. said she was ‘in on the plan’ but she just got pizza.
