One renowned as the antithesis of punctuality, and whom takes the act of slacking to an entirely new dimension. The incredible level of slack achieved by this "schlade" has reached such epic proportions that the slacking bar has been raised for stoners everywhere.
"I had plans with schlade at 7:30 so I showed up at 8:45 and he still wasn't there! I guess you can't schlade the schladester."
