200 percent

An athlete that has too many hearts for one person.

An athlete that says he (or she) is always giving 200 percent, or says something like I got two of those when somebody asks him (or her) about heart is a little bit suspect. It makes you wonder who else's heart they cut out and put in his chest, and what they had to take out of him to make extra room for another transplanted heart. It doesn't seem like a guy with 2 hearts would be in good health most of the time, it seems like the extra heart would blow out like a speaker at some point.

200 percent

Double everything something has.

Zeus, the uber competitive athlete, was always trying to turn up both of his/her 2 hearts to 200 percent and thought that most people were cowards for not giving as much as him/her, while most people thought Zeus was a fucking idiot that tried to take something like a stupid fucking game or sport to a level of desperation and calculation that they were never meant to be taken to, since it became more about trying to run people over than having a good time by that point, and that didn't interest people any more than pointless battles for superiority did.
