Chittling Grease is created after a man has had hot sweaty frog sex with a woman all night long and the next morning, without taking a shower, he goes and plays basketball. Once he is finished playing basketball he has now mixed a woman's love juice with some nasty sweat between his balls and his legs. This will create a nasty, funky thick, brown substance and the smell is equivalent to that of chittlings.
Joe: Did you hit that last night?
Frank: I hit it all night and got up and played basketball.
Joe: I knew you smelled funky why you were playing.
Frank: Oh yeah, I got some good old chittling grease right now. Here smell!
