afterclap -- That last person/people who keep(s) clapping after everyone else has stopped.

normally parents, but it could be die-hard fans etc.
*Large chorus of clapping"

Mom: "Did you hear little Billy's singing?"
Aunt: "Yes his voice really stood out"

*Mother and Aunt only ones clapping still*

Bystander 1: "That afterclap is lame, their kid totally sucks, it was a choir of 200 kids!"

Bystander 2: "Yeah afterclap kills a show sometimes.."
