the official title used by fuck buddies to supplement other commonly used titles such as Mr., Mrs. or Ms.
A couple goes to see other friends at a bar and a guy introduces a girl who came with him:
Guy A: Hi guys, this is Fbs. Smith.
Guy B: Wait, really? What does that stand for?
Guy A: You don't know, we are just fuck buddies!
Guy A: Hi guys, this is Fbs. Smith.
Guy B: Wait, really? What does that stand for?

Full body shutter
This term originates back to the summer of 2007. Originally an involuntary spasm when touched by a disapproving female, it has since been adopted by others as a formal way to communicate "that's really gross", or "that's fucked up."
It can be used by males and females and should not be overused. If a person is incapable of shaking the entire body in disgust, they are not allowed to say "aww, fbs", and are excluded from the fan club.

Jen: OMG, Stacey is giving Phil a hug. That bitch!
Jon: Yeah but he's having an fbs, he's clearly not interested
Jen: What a relief! I'm glad fbs exist!
NOTE: The above example is based on an extremely true story. I swear.
