F.B.S. (Fat Bitch Syndrome) 

When a heavier woman acts in ways that aren't normal or positive to garner any attention she can from others.

"Last night Bertha was starting so much drama because she wanted Rick to notice her and she wanted to keep his attention off of the better looking girls. That hooker has serious F.B.S. (Fat Bitch Syndrome)."

They should make north I-94 a toll road so we can collect some money from those F.I.B's who come up here every summer and act like they own the place.

F.R.B's 

F.R.B's stands for Free Range Boobies. Just like free range chickens the girls allow their boobs to be roaming freely under loose shirts.

Hay dude! Look at the major nipple reaction (MNR) on those F.R.B's. Must be the summer breeze.
