When someone is hard to please; they always expect the best, and more; good is never enough; always room for improvement

The student could've done better (99% on test); 2nd place out of 100; 'they could've done better'; I like that person, but their laugh bugs me. I'm such a "hard marker"

A very hard to please person; they're always finding faults.

Hardparker 

Noun, derived from the verb hardparking. One who has all manner of track and race modifications on his/her car, yet never goes to the track or auto-x.

"Jim's 325is with the M-tech body kit and Moton coil-overs and Turner sway bars, and that finned diff cover on the 3.23 LSD from Bob's totaled '99 M3, and the roll cage with fire supression system, and the 3.5" HFM and all his shizz under the hood is so hot right now."

"Yeah, dude, too bad he's a hardparker, if he learned how to drive that car would kill at the auto-x."
