A douche-helm is a leader in douchebaggery. This person personifies everything douche to the extent that just being around said person will make you a douchebag.
A douchehelm will sometimes gain control of an audience and hypnotize by presence alone. Everyone will quiet down and listen to his every word as if he was a great leader yet there's this lingering itch in the back of your mind wondering why the hell everyone is listening to this douchebag.
Dr.Phil, Kanye West, Ryan Seacrest
"Ever since that douchehelm showed up the entire team turned into major nancy boy cunts."
"If you see a douchehelm, run the fuck away as fast as you can before he infects you with gay."
