MatPat 

An amazing YouTuber and Diet Coke addict who makes theories about video games and movies. He also does livestreams with his wife, Steph, at 4pm PST every weekday. His channel started out with him as a dorky theater kid doing auditions, and while he's still a dork he's a cool dork. Also pretty cute if I do say so myself.

"Hey, who was that nerdy YouTube guy you're obsessed with again?"
"Oh, yeah, that's MatPat."
