For any of you you don't recognize many things written in that list:
In the past years (2006-2007 or so), there was a website called masterclassfreestyle. The founder of the site was Edward Yoon, a Korean - Canadian freestyler (some of you may have heard of the guy). Long story short, he made the list of every freestyle trick he came across, and, since he was quite creative, he created some of the tricks himself (hence the EATW = Edward ATW, and YATW = Yoon ATW). Now we all know (and I think he also knows) that these names are outdated and belongs now to other tricks entirely. But it has been a long time since he even checked that site, and therefore the site remains, but it's like a Velociraptor Mongoliensis in the modern Gobi Desert (outdated).
That's why most of the tricks on the website itself is not compatible with the modern freestyle scene no longer.
@ PannaFootballTube: my friend, if you try to do a dictionary like this, why not start from scratch, avoiding other people's stuff? I doubt that you even had Yoon's permission to copy and paste his stuff like this. Just create your own list of tricks (do your best) and then ask other people to fill in on the tricks they know. That'll be way better IMO.
