Whadda yall heard on American stereotypes?

Since I am from the US, I want to know some of the stereotypes that you have heard. Also, as you can tell I can speak properly but that does not mean that I do on a normal basis. Yall heard! Aint no thang but a chicken wang! Ya lo sabeis! In all seriousness though, please I wanna know what yall think. And I'll correct yall when I see an incorrect stereotype.
