Nah, they must have this done before at home or at someone else's party. There's always be a toxic guy talking down on another dude at socialized gathering. Not because of numerous alcohols he consumes, he's just toxic treating everyone around him like dirt. Similar incidents at the HNY or a large party after festival.
Back to OP video. Not sure which dude started first, but I'm very sure there's a time a guy will get angry at his partner without understanding other guy's difficulties to perform when he's still a rookie. When that happen, the rookie guy receives the angry vibe and the rage escalates. Lol
