Replying to Steez

Question, my and my riding buddy have been arguing for a little bit about the parts of speech pertaining to the word steez.  Originally it was clearly an adjective.  As in "that was a steezy blind four" or "thats a steezy tall tee."  The questions are, can steez be a noun?  As in, "That jacket has so much steez"

The big question is can it be a verb.  As in "I steezed that down flat down rail" or "I was stezing all over that triple jump line"

Thanks guys.
