walkin and talkin, example: and one time i was so hot, i was cool!  like a level one can rise to.  in many peoples cases there levels would be, from lower to higher. "knucklehead, ..moron, ...idiot", ..and as you go higher you add adjectives, like blooming, frickin, and so on.   damn, i am hot this morning, and later on i´ll be cool, get the picture all you (take your rank/level from list above.)? ´´paz´´
