A 9-year-old rapper from Massachusetts named "Lil Poopy" is stirring up some controversy, because a lot of people think his music videos are too ADULT.

They're upset about the end of one of the videos, where it shows a woman in spandex pants, bent over, and he's spanking her.   They also don't like that he raps about how, quote, "coke ain't a bad word, it's only soda."

Child services is even investigating, but it's not clear if they'll do anything.  A lawyer for the dad calls it "absurd," and thinks there's a racial element to it.

(He raps about "coke" at 1:32, and spanks the woman at 2:28)
