Is a Swing Man in the NBA someone who likes Brain Setzer Music?

Question

or someone who engages in "adult activity"?

Answer 1

it could be Vince Vaughan listening to Glenn Miller on his iPod while playing both forward and guard...

Answer 2

Lol, a Swingman is a basketball term defining a player who can play both the small forward and shooting guard positions; and, in fact, swing between the shooting guard and small forward positions.

But given history of cheating on their spouses, your latter choice might not be too far off.  

Answer 3

Swing Man in the NBA is someone that can play either the forward or guard position. Another case is a Small Forward on offense will switch to a Shooting Guard on defense if the matchup is in their favor.
