PWG

Acronym for: Potential for Weight Gain.

An estimate of a girls future size and/or weight. Dead give-aways are big ankles, calfs, legs, butt, eating habbits, and most impotantly what her mother looks like.

She looks good now, but her PWG is off the chart.

You ought to marry that girl, her PWG is low.
