I don't get the marketing angle here. So they think that all black people have great teeth?
Well, many in Africa do...well the one's that don't use sugar in the European sense...apparently, when Blacks in S. Africa started having a more Euro-centric diet, which was heavy in sugars, they started getting more cavities, more plaque build up, etc.
Also, in some African countries, there is a tree, a stick, that many used to chew...apparently this "chewy" twig had many health benefits, especially for the teeth.
Don't know about that. Got a mid forties chinese lady on my job that has made it obvious she wants my dick.
You probably are misunderstanding her...she is probably saying "Get...Out" or "Quit"
