Mackin Handshake 

When you meet a girl at a bar and end up fingering her at the bar or right outside the bar in an adjacent alley. It happens so quickly, it is practically during the introduction.

Person #1 - "Hey where did Mark go?"
Person #2 - "He is in the corner giving some bitch the Mackin Handshake"

When your boy used to be a stud and mack on all the ladies but now he's docile and polite

Person #1 - Yo, is Mark still a savage?
Person #2 - Nah, he's on that new mackin handshake because he has a girlfriend now.
Person #1 - Goodnight, sweet prince :(
