PHBA
Acronym for "Pin-Head, Buffalo-Ass", particularly as a descriptive term for a woman with a small upper body and broad hips. Usually applied to caucasian women and predates the acronym PAWG by approximately twenty years. Also, a PAWG may have large bosom or midsection, whereas a PHBA is small framed from the top of the hips upwards to, and including, the head. PHBA's tend to gravitate towards careers in k-12 education.
