FBD

Free-Body Diagram
A picture, drawn in physics classes, that shows each force acting on an object. The object is usually shown by a dot, and only shows the forces acting on THAT object, hence the name, "free-body" diagram.

Let's just draw a FBD on the board here of a ball rolling down a ramp

FBD

FBD = full blown drunk

When you've gone past the point of tipsy and on your way to total slurring.

Krissy: oh I couldn't have another drink. I'm already tipsy.
Adam: Tipsy?!?!?!? You're FBD!!!!

An fbd is a facebook douchebag. This includes males with too many friends at least 150 of which they will never converse to or a female with an excess of friends at least 200 of which they will never converse with

That guy thinks he is cool because he has so many "friends" on facebook but he is really a fbd.

FBD

FBD or Fuck Boy Disease is when a girl gets attached to a fuckboy after him 'hitting her up' or 'sliding into her dm's'.

Him: Hey girl 👅
Me: *to self* "Not trying to catch a case of FBD!"
