Hadorken
A person who thinks they're a Street Fighter champion and will cuss you out if you don't know what a Hadoken is.
He cussed me out in a DM because I spelled 'Hadoken' wrong.
He called my friend a 'literal disgrace' for not knowing the difference between Ken and Chun-Li.
He once beat a guy up in a park because he thought the guy was a Street Fighter noob.
