What you're supposed to say after every line of the birthday song.

The guys say boom
The gals say ching
and we all say cha cha cha
At every Cha-cha cha you're supposed to do a supposed to do a cringy dance step
Birthday Kid: please don't tell them.. do the Boom-Ching-Cha-Cha-Cha and I WILL END YOU
Guy: *starts singing happy birthday song* C BOOM!
Gal: CHING!

Everyone: Cha-ch-
Birthday Kid, glaring at guy: 🙄🔪🔪🔪
