Pool: Nice Knowing You

Usage when a character does something stupid with a lack of foresight and gets punished for it. Foreshadow of impending doom. Can be before or in process. Usually comedic (to the viewer).

It is not for pictures that has a 'You gonna get raped' feeling but more of a 'I have a bad feeling about this' or 'I wouldn't be doing that if I were you'

Bonus if the posts cause the viewers themselves fear.

Update: Ok I am cutting the problem in the bud: it seems that people are mistakening Badass with Nice Knowing You. While it is possible for those two be present in the same image I want people to know that Badass=/=Nice Knowing You is not true.
Sure the character is holding a giant sword with facial shadows created from a light source underneath them may be badass, but in no way is it Nice knowing you.
