ka-checca
A stupid, loud noise used to celebrate something dumb, usually when a Checca is around and they’re too dumb to know better.
Ka-checca! I just ate three burgers for breakfast. I’m going to explode.
Ka-checca! I just failed my history test. I’m the worst student ever.
Ka-checca! I just got into a fight with my brother. I’m a total idiot.
