A nickname given to Black American females who have high traces of mixed heritage (Usually of both Native American and European), via her long - but still soft - hair, light and fair skin complextion, other phenotypes that differentiate her from other generic black girls.
Generic black girls will approach them and give them compliments, tell them how they wished they had long hair like theirs, comb their hair... Behind their backs, most black girls are really envious of such girls.
At first glance, people will automatically assume that these girls are half black and half something else. Though they are of high mixed heritage, girls nicknamed Pocahontas most likely classify themselves as black/african american.
I'm black, but my mom has Cherokee heritage and my dad Irish, so I don't have generic black phenotypes. I have been dubbed "Pocahontas" by a lot of people, and thus, I have been adored and rediculed at the same time.
