Among lower class blacks that like to down their own people, Uncle Tom has fallen out of favor with the young. Now only older blacks, and white folks use it. House N----- seems to still be pretty popular. Oreo/Oreo Cookie is done, seems to have gone out long ago.
C--n is the newest and most popular one with the youth now a days, it's also used in a much nastier way it seems. Bed Wench is popular for interracial dating black girls, but it seems to be more of an internet thing for now.
