This can only happen when two best friends are giving blowjobs simultaneously. While performing they are told to look up and they are surprised to see each other.....
Dexter: Carol is going to be giving me skull at 7:30 tonight. BFF mouthful?
Josh: Yeah Sheryl will be home by 5. I can make sure she's blowing me at 7:30.
Dexter: Ok perfect. I'll send you the facetime invite at 7:32. Just accept the call immediately and point the phone at her. I'll make sure to do the same.

Josh: This is going to be especially funny because Carol and Sheryl are best friends.

By adding the suffix "est" to BFF you acknowlege that one person is your bestest bestest friend forever.

The suffix is derived from the adjective-chain big, bigger, biggest. Increasing in size until it can increased no further. This gives a new chain of BFF, BFF-er, BFF-est.

A guy who always gets in the way of two girlfriends hanging out.

Most likely it is one of the girl's boyfriends who makes plans to hang out with her during all her spare time, leaving no time for the best friend to see her.
Girl 1: Hey do you want to hang out on Saturday?
Girl 2: Sorry, my boyfriend already asked me.
Girl 1: Again? Uhgg he's such as BFF Blocker!

Example 2:
Girl 1: So, girl's night out! What are we going to do?
Girl 2: Actually, my boyfriend wanted to come too. Hopefully that's okay!
Girl 1: Didn't you just hang out with him all day? We need BFF time! He's being a BFF Blocker.
