The athlete who always gives 110% during practice when it's not necessary, just to show up their teammates. Is usually the worst player on the team who never gets any playing time, only in practice. Generally unliked by their teammates for obvious reasons.
Olivia: "Hey Rudy, take it down a peg it's not even a game. No need to be a practice hero!"

Emily: "But practice is the only time I get to play!"

Chelsea: "Yeah, Helen Keller sees more playing time than you.."

Practice Hero
A certain Athlete who feels that it is his or her responsibility to make everyone else look like shit. Usually found listening to Christian Metal (for Jesus-fueled adrenaline) or jerking off to running videos. A Practice Hero never stays up later then 8'o'clock, and rarely socializes with anyone other than their right hand.
