Ten and two tweaker twist
When a crystal meth shard is put into a meth pipe you have to purge out cutting agents and allow the shard to liquidate then allowing it to reharden inside the bowl. To spread out the liquid meth you rotate the pipe in a motion from 10 - 2 on the clock. Back and forth in your mouth first exhaling blowing out a dragon cloud bigger than your vape and then inhaling to get high. This is in reference also to the amount of time you will most likely be high for, especially if you're a chronic user. Another main reason for the twist action is to distribute heat evenly to the round bowl.
Tweaker one, "Hit that pipe with a twist dude!" Tweaker two, "You mean with a ten and two tweaker twist?" Tweaker one,"yeah broskeet!"
