Who knows what gestures mean? Some seem definite but are they? Are they really? To illustrate, I shall post a short film taken by my wife. It was made last year of me performing a private retirement dance. My son posted it on Youtube and called it, "Geezer dances until told to stop". They thought it might make me a famous dancer, which I considered optimistic over a career of only 16 seconds.
Turns out the 16-second gravel dance gathered over 180 views, which is famous enough for me, but recently I was told I could sensationalize the title and greatly expand my audience. I am uncertain of the process, but consider "Geezer convulses and hoarks up a hip-bone" a strong favorite. It wouldn't be truthful, but those expert in dance gesture assure me no one could tell until the end of the clip.
