(Pronounced Doo-shay') A combination of Douche and Touché. What you say when you realize that you said something so douche-y. Usually said while cringing that you realize what a douche-bag the other person thinks you are. Very applicable to telling people you are rich or went to a top university. The emoji of slapping your forehead is used here.
I was trying to connect with my new next door neighbor about biking. So I was telling him about my bike. I said "I miss riding that bike because it is in my apartment in Paris." Thus slipping in that I have a second home overseas. Douche`!
