Premature Chimulation 

The early execution of an alarm, bell, electronic tone or device used to measure time or call organized meetings or events to begin or end. The early execution can occur whether by improper programming or human error.

"President James rang the closing bell early, not allowing the Superintendent to talk, and the premature chimulation resulted in disorder within the club."

Premature Chopulation 

When you chop someone while playing Tesla Chop but it in fact was not a Tesla. The chopped party receives two chop backs to be used immediately.

That wasn't a Tesla, it was a Honda, so that was a premature chopulation.
