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 = 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!!!!

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 👅
