Overheard during a Tricking session at the gym
Tricker: "Bro did you just see my awesome triple cork?"
Gymnast: "Yea man, it was almost like a layout with 3/1 twist. Except that your knees were bent, your toes weren't pointed and you rotated off-axis. Did you see my punch double front?"
Tricker: "Pretty sure that's impossible bro."
