Stands for Recreational Powerade User and refers to those who drink the sports drink (powerade) on a casual basis, when it is only to be consumed when one is participating in strenuous physical activity.

RPU's are generally addicted to powerade, as it is full of sugar and contains many artificial colours and flavours, making it taste good. The sooner RPU's start waking up to the fact that these drinks are NOT to be used on a casual basis, the better off society will be health wise.
Matt: See that guy over there, why's he drinking powerade? He's not exercising.

Harold: Ah, bloody idiot. He sure is an RPU
