The attempt to clap in applause at some event but very few people, if any, follow your lead. This can also apply to the related scenario when one tries to lead out in a clapping rhythm at some musical event or figure skating competition but also fails to gain a following.
"After my last clap abortion at the downtown rally, I've decided to call it quits. It's just too embarrassing."
