The woman who alleges Bill Cosby sexually assaulted her at the Playboy Mansion is getting revenge with a rap diss track that's so bad ... you can't NOT listen to it.
The L.A. County D.A. rejected Chloe Goins' case last week, saying Cosby had an alibi, plus the statute of limitations had run out. An angry Goins decided to fire back at Cos by getting in the studio with a producer in Southern Cal ... according to the Daily Mail.
"Bill Cosby: Diss Record" starts off ... "Hey Bill, I guess you think you're pretty slick. Making sure you drugged us, thinking that we would forget ya. But we didn't, and now everybody knows."
