Here it is, to straighten it out for the non-mackers (symps)

A mack is a man who can woo a female of the opposite sex with his seductive actions and domineering manner. As a tribute to his skills, the woman will often do whatever he likes. This includes actions such as paying for meals and even rent.
I got that woman sprung man! I was a straight macking and she even paid my December rent. We are going to Friday's tonight, I'm eating steak tonight!
