Form Factor B 

A woman with a belly that sticks out as far her tits do and sometimes beyond them. From the side she will resemble the capital letter "B".
Sometimes (inappropriately) used to refer to a woman in late pregnancy.

Dude, just cuz my girl is knocked up, that doesn't make her a Form Factor B. Once it drops she'll be back to normal.
