Lol he does seem pretty cocky... Just the way he reacts when he lands something. Idk. Sick riding though, loved the picnic table to roof wallride! But damn he's gotta work on his flairs because I keep thinking hes going to hit his head.
I don't think it is cocky. I'd say it's just excitement and everybody has a "style" or whatever you want to call it. I'm much more okay with hand gestures than watching sponsored kids launch their scooters out of anger in a professional edit.
Impressive stuff for sure in that video. I wish he'd wear a helmet to flair that low, though.
