OBFFS! That was totally uncalled for!
OBFFS, just open the goddamn door before trying to enter!

Losing touch after college, Erin and Trevor reconnected several years later on Facebook and now, communicating strictly via computer, are OBFF.

ERIN and CARA were OBFF's, they had known each other for years, but with life being so busy, it's easier to stay connected through social media.

She was my OBFF before Jennifer was my BFF.
