Coach
A man or woman who has several partners of the opposite sex who all know about each other and willingly play their role. The partners are deemed to be on the roster. This is different from a player because there is no lying or misleading involved. Phrase made popular by Fabolous in the song "Can't Let You Go"
Guy 1: "You're the biggest player I know."
Guy 2: "I am not a player, I'm a coach."
Guy 1: "What's the difference?"
Guy 2: "I never lie to these females and I keep a whole roster of them.

Fabolous: "When the starting lineup ain't playing right, I come off the bench with her."
