Reason #93: The A Cappella Bop
The a cappella bop—a repetitive bend at the knees, usually (and hopefully) to the beat of the music, sometimes from side to side, is the both the signature and the default dance move for a cappella performers. Since groups became (self-)conscious of the phenomenon, some have seemed to purposefully step away from it in favor of prioritizing blocking over movement, or more intricately choreographing the duration of their songs. And yet, for many, if not most groups, the bop persists, used either obliviously or with a very intentional sense of a cappella pride.
I love it!
