Kachilson
The loud, angry noise that comes from a Wilson getting struck by lightning and you're too lazy to say anything else. It's basically 'kachow' but with more swearing and less coolness.
Wilson got hit by lightning and I said 'kachilson' because I’m lazy and also mad.
Lightning hit Wilson and I shouted 'kachilson' like I was in a fight.
I heard a Kachilson and it was Wilson getting hit by lightning. I laughed because he was stupid.
