gigantism 

A physical condition where a chick is quite large (often 6 ft or taller) but not really fat, thus still attractive and very fuckable. Small men are often intimidated by such women which is unfortunate for them, because they are great lays. Women's volleyball players often suffer from gigantism.

"Damn, did you see those fine-ass honeys in the 2-on-2 beach volleyball tournament? They have gigantism, but I'd fuck the shit out of all of them."
