look up any word, like cunt:
something so amazing and awesome that neither gnarley or legit can be used singularly. so they are compiled into one simple word

p1"dude skyhigh sports is gnarlegit"

A shortened version of the word "Gnarly" combined with the shortened version of "Legitimate". Combining the two into a single form increases the "realness" and "coolness" of what is being described.
"Dude, did you see that Nissan GT-R with the AMS Alpha 10 Performance Upgrade Package?"
"Yeah! It has 1100+ horsepower. It's pretty gnarlegit"
