1. To introduce oneself with douchebaggery, by bragging about meaningless accomplishments in an attempt to impress others.
“Hi there, I’m Bradley. I used to write for the Huffington Post, I own over 50 domain names, I work on several websites, and I’m close contacts with Mark Cuban and Grant Cardone.”
“Thank you sir. I’ve allowed you to introdouche yourself…now get the hell out of my face you douchebag!”
