Never tried actually. Angry Dragon? Is that like similar in some way to a Death Grip?
Ok I've given it approximately 45 seconds of thought, and the best option I came up with was a rubber band, placed reaaaaally tightly around your arm. I mean, if you wanted to you could wait 5-10 minutes sitting on your hand for 15 seconds of action, only to have to wait another 5-10 minutes... But the rubber band would probably work better. Or a shoe lace would do, but it would probably hurt a bit more, you'd need something to increase that area at which pressure is absorbed by your skin from the tension in the string or shoe lace.
Nevermind. Just use a rubber band.
