Dunno, but went to this reggae show one time, looked around and realized over half the people there were these thug nigga looking niggers with dreads with fat white blonde chicks. Went outside for a smoke and literally the whole block was full of niggers with fat blonde chicks smoking weed. Like every single one of them were with fat blonde white women.
1) Black men, on average, have bigger cocks. Big girls need big cocks because normal white ones can't fully please them. Not to mention black men generally have low standards.
2) In African societies, larger women were usually rich, because if you're fat obviously it means you can afford food more than others. Tribal men would seek these women out and court them to become rich once they married into the family.
