Kahwaji
Kahwaji is just another word for donkey. It's like saying 'horse' when you mean 'donkey.' You're probably the dumbest person in the room if you're a kahwaji.
My friend said I was a kahwaji because I 'ate all the pizza.' I told him he was a kahwaji because he 'ate all the pizza and then said he was full.'
My brother called me a kahwaji and said I was 'stupid as a donkey.' I called him a kahwaji and said he was 'stupid as a donkey who ate pizza.'
At the park, a kid said I was a kahwaji. I said he was a kahwaji and he was 'stupid as a donkey who didn't eat pizza.'
