Black Man Taliban. A black guy wearing white pajamas from head to toe, sandals and a kufi hat yelling gibberish noises as if to enunciate the noises made by the terrorist group the Taliban.
A random guy runs around in the mall dressed like above and is probably high or mischievous.

Random person:"That guy over there is dressed weirdly."
