I know you're playing devil's advocate, so I can appreciate that winded post.
But I've been skating for well over a decade, so I dont need tricks explained to me lol.
It is just like you said with the 5-0/salad thing tho. The way I see it, if a dude lands his front truck on a rail with his tail already tweaked out, thats an overcrook in my book. My book is written by me and is, therefore, unofficial. Its just when I think back to belly-flopping on a 6-stair handrail trying to land my first "fs overcrook" it pisses me off a bit to hear folks call it a nosegrind. Cuz when I didn't swing my tail over the opposite side of the rail that I came from, it was a lot easier to do.
But when I was kicking my board forward and calling it a dolphin flip only to have some kid tell me; "Thats a Murder Flip!" another; "Forward Flip" and yet another; "DONKEY FLIP!", I thought, "Awesome!". Cuz I knew we were all talking about the same thing, I liked being able to refer to it so many ways.
A names a name, and a sweet ass trick is just that.
