3. Cam'ron "Takeover (Freestyle)" (2006)
Lyric: "I send you a tape of your sister and your mom kissin'/My dick that is, see how foul them bitches is?/Four minutes they gonna lick my kids" (1:14)
Now this is just not nice, not to mention there's a whole lot of issues at play. First of all, someone's mother and sister, who happen to work together, are having inappropriate relations with each other at the workplace: Cam's Crotch. Presumably the son/brother in question is the head of human resources at Cam's Crotch, because Cam promised to send him video footage of these workplace acts of incest. And based off of Cam's critique, these women will probably get a talking to. But if there's any good news, it's that there's only four more minutes until their shift is done.
