Attempting to mack on another person's significant other by talking bad about them behind their back.
If you've ever had a girlfriend/boyfriend leave you and hook up with your best friend, you can be sure some dirty macking was going on while you were dating your ex.
John: "I'll be right back guys"
Dirty Mackin' Bob: "So Cindy, did you hear how John was talking to that slut Suzy when you were out of town? He doesn't appreciate you."
Cindy, John's Girlfriend : "Don't try dirty macking on me just cause my boyfriend's not here. Aren't you supposed to be John's best friend?"
John comes back and slams dirty mackin' Bob in the face with a shovel

A band who's members included Eric Clapton, John Lennon, Mitch Mitchell, Keith Richard, Yoko Ono, Jimi Hendrix(?)...and performed at the Rolling Stones Rock and Roll Circus in 1968.
