A term used to make fun of Chrome (Google's Browser / OS) Fanboys. Popularized by a guy named Redlid who shows up on various forums when Chrome is mentioned and calls them Chrome Dickheads, usually using very poor English.
User1: I use Chrome!
Redlid: User 1 has Chrome Dickhead for 10 years in neighbourhood, asshall!
User1: My dickhead isn't Chrome.
