The urge to be first, the center of attention, or the front runner in any aspect of day-to-day life, the term deriving from the multiplayer video game position of "player one".
Fred has player one syndrome: he always has to have the first controller, otherwise he gets upset and doesn't play.

Marge has been really controlling lately. Maybe she has player one syndrome?

Why does Layla think she can get whatever she wants if she throws a tantrum? She's such a player one.
