A very hot and attractive girl, often quite feisty who while in the process of working out sweats profusely. Often seen at one's local gym, on the treadmill, or doing a turbo-kickboxing class.
"Damn girl, you're such a sweatmaster. Watch wear you're swinging your arms."
"Hey sweatmaster! Don't forget to wipe down that machine. You're cute, but still."
