Black ladies in the south use grits to punish a cheating husband. You boil a pot of grits let it cool just a little and throw it on him. Burns the crap out of him and something about the grits cuase them to stick to you so you get a really really nasty burn.
One of my black co-workers come home drunk and bad mouthed his wife in front of their kids before he passed out. He woke up the next morning with " I will Respect Nikki" carved down his arm deep enough that you can almost still read it. He says he probably deserved it and if he pissed her off that bad he's lucky to be alive.
