What guys say when one of their friends is flirting with a girl and she's flirting back. A congratulation of sorts. Usually paired with a nod, high five, or thumbs up. The girl is usually blatantly unaware of the meaning of said exchange.
Guy: *flirts with hot chick*
Hot chick: *flirts back*
Guy's man friends: Wow, nice mack!
#flirting #score #high five #thumbs up #nice!
