A KompAppella
A KompAppella is when people sing like they’ve been yelled at by their mom, dad, and the principal all at once, and they make up fake instruments using just their face and their feet.
My KompAppella was so bad, my teacher said I should be sent to jail.
At the concert, my KompAppella scared the audience so much, they all ran out.
During my KompAppella, I clapped so fast, my arms felt like they were on fire.
