I think we all need to use the phrase "sweaty awesome" in our everyday lives until it makes it's way onto a network sitcom.
The probably is, it takes a special sort to pull off being "sweaty awesome". Like, if you were to say, "Redz is sweaty awesome.", I'd be reasonably sure you'd need to adjust your goggles or something. I'm more likely to draw a "Sweaty smelly", description.
But I guess in the context of it said in just a random positive way like "COOL" or "RADICAL" or whatever the hip way of saying something's great is that I'm way out of touch with..."Oh man, you're new sneakers are
sweaty awesome." Hmmm?
