I'm a bit confused, if it's a technique you have a name for, then doesn't that mean you know what it is. It would be good to link to the actual position in the video.
You employ a lot of kweif tonguing, ja ?Ask twenty players for their definition of "half tongue" and you'll get twenty one different answers!
Believe it or not, another technique I sometime use is to move my tongue OVER the tip of the mouthpiece. It kinda-sorta gives a tonguing effect, but obviously not a direct tonguing of the reed as we usually do it. Plus, the chicks dig it.
