NSF

Near-Sighted-Freak
-Someone who has poor vision due to staying up very late while yelling at their sisters about nonsense, and during the day is an absolute mutant of the human nature. They are very aggressive and like to verbally arrange fights, but never actually follow through. All in all, they are people who you should avoid at all costs, although it is very easy and amusing to harass them.
MAN 1-dude, my neighbor over the weekend woke me up at 3.30 PM by yelling about markers, then the next day he threatened to tear both my ACL and MCL with a toothbrush, but couldn't see me very well.

MAN 2- ouch, you've got a bad case of an NSF as a neighbor.
