best friend for awhile, or someone that you've befriended because you have to/for selfish purposes and as soon as you don't have to see them a lot they will no longer be a best friend.
kate: so how are you and the new roomie getting along?
madison: ugh she's so annoying, but she's my bffa because she always gets into awesome parties and takes me.
Beautiful from far away. A girl that looks gorgeous when she is far away, but she turns out to be really ugly after a closer look.
That girl is gorgeous! No, wait... Never mind. She's just BFFA
