Matt's description in Super Best Friends Brawl - Super Smash Bros

Matt was Pat's foil, and as such, he was not nearly as smart or good as Pat at video games, especially when it comes to navigating. However, Matt often fucked with Pat, and frequently got him with savvy and well-timed "your mom" jokes, although they died down substantially as time went on 

He is a smooth ladies man who is both charismatic and charming. He is extremely patriotic towards America, despite being Canadian. In episode fifty of the Super Best Friendcast, Pat stated that Matt was stupid, to which the latter agreed, making it canon, according to Pat and Woolie.
