The Self cheer. When you 100% need everyone around you to know, that you know how brilliant you are at skateboarding. Skateboarding is an arduous venture, trying a trick for over and hour may seem ridiculous to an outsider, so cheering when you land something insane can be justified. Pro tip: next time you land a tre flip bolts look your mate in the eye and just say “textbook” before skating off. I have found this to be the most effective self cheer technique.
