I've done that "once or twice"Oh i just have to find out if i am the only one to do this sometimes.
Sometimes when i vape on the bb i accidentally close the air holes holding the bb in my hands. And then when i drag it feels like a very tight mtl draw but then i remember the air holes. And i get a short little chukkle to myself about it and then i shift the bb into another position. And then i vape on and love the flavor.
My default grip has now adjusted to a position where that is not likely to happen anymore
