(DON'T CALL IT BREAKDANCING) I don't know much about b-boys and b-girls (henceforth "b-persons") except (1) they prefer you not call what they do "breakdancing" and (2) watching b-persons spin, flip, pop, lock, kick, freeze, drop, and glide to everything from vintage hiphop to Paul Simon is like watching a magical hybrid of dance, gymnastics, and martial arts. Tonight, at midnight, the final 11-round battle of an eight-week tournament will decide the city's foremost b-personage. It's gonna be awesome.
