FBC
N. A name given to a group of overweight office bitches who eat lunch together everyday. FBC can also be called Fat Bitch Club. Usually the bitches are women but it's not necessary to only have woman in your FBC. Some FBCs eat healthy in order to help each other loose weight. In most cases they start healthy but usually blow it by either eating too much. Some FBCs do a snack of fruit salad in the mid to late afternoon. Some FBCs have a token skinny person. That skinny person is usually anorexic and thinks she's fat.
