A man (or in this modern and politically correct time frame, a woman) who indulges in the pleasures of various sports, usually of the physical persuasion. This may include soccer, hockey, sex, football, rugger, cricket or ping-pong (this one is iffy). Sportsfellows tend to be easygoing (case and point, sporting) though when pushed via adversity, may display streaks of hypercompetivity.
Sportsfellows play sports on purpose.

Billiards is not a sport.

Get the Sportsfellow mug.
To be in possession of an excess (to the norm) quantity of fluids. This potentiality is applicable in a number of situations, such as in the case of a sportsfellow who brought more than the usual amount of water, someone who bleeds a lot, or someone who discharges rather a large load.
1. Hey man - thanks so much for bringing all this gatorade - I always forget mine. You're superfluidous!

2. "Shit man, that's a lot of blood!"
"Man this is nothing - I'm practically a haemo!"
"Dude. You're superfluidous."

3. Man, I was so superfluidous last night. Yeah, I nut.
