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.
