Also, one who is a
flirt, one who has
sex or
intimate relations with many is defined as a
player. This is an extension of
adrianthomas's 2nd point, a player is someone who plays people, to make the
victim think that the player is in
love with them, then the
player manipulates the
victim to get what he/she wants (usually sex), and
dumps them later.
The played are often left with a
broken heart. Cruel isn't it?
