A question.
You know the drum emphasis after someone makes a joke... that ba dum Bump?
What's that called?
It's not a drum roll. Or a drum beat.
Erg.
At the moment, I'm going with: Charlie mimed a drum response. But that's definitely a rough draft place holder.
Anyone? Bueller?
ETA: And we have a winner. Except it wasn't actually a contest. The word I was looking for was rim-shot! Thank you! I swear, I'm losing brain cells hourly these days...
