Nosepicker

No pun intended - I think most of us have picked our nose at one point or another. But there is a nervous tick/thing that some can't help themselves and really go for it. Of course that is way gross - so try not to do it in public if you are inclined to do it anyway.

Also maybe piling up that stuff .. not the best idea ... unless you plan to do a horror movie about it. I do think that the movie takes a bit too much time, we know where it is going anyway ... and the sticky stuff does not actually look like .. the stuff he'd take out of his nose. It looks more like food stuff - not sure if you mind ... I reckon it was done out of taste - no pun intended. Anyway, interesting idea., well executed (yes another pun)
