Surprisingly, "bunch of fat bitches" is not a term used to refer to overweight women in a derogatory manner, although it could be used that way. It is more often used to refer to just about anything in a negative light when the referrer can't think of anything wittier to say. See brainfart.
Doesn't always describe something in the plural sense. (See below).

a very corpulent, whiny, angsty girl. She loves pizza and tends to weep when she doesn't get her way, or is underfed. She can often be spotted alone, or with people who pity her and wish to feed her for the sheer sport of it. She can often be deciphered by her grotesque rolls of fat, and and unusual amount of chins.
Someone forgot to feed the agonized fat bitch. Look, she's crying so much her chins are gathering the tears.

Fat Bitch Friday is when you go out on a Friday night and are surrounded by fat bitches at the club. They stand in line snacking on pork rinds and trying to flirt with the doorman to skip the line, but end up having to wait. They always travel in packs.
