Grimm Green-i love when he takes a "toot". And why does he always seem to get a head rush everytime he tries a new flavor? I USED to be fooled, but now that I've been vaping for over a year I know that most vapers hit it off and on all day and the only way to geet a rush is if one hasn't vaped in HOURS (like upon wakening in the morning). Funny guy.
From what I can tell, he takes long drags at high voltage. I don't have much experience with that (using 3.7), and my lung capacity sucks, but I could imagine that would give a rush.
