Neisser 

A Neisser is a very angry person. He is not to be fucked with. He could and would kill you if you made him mad enough. A Neisser also isn't very smart but he's great in bed ;)

Some guy: Hey look it's Neisser
Some other guy: Oh shit, don't make him mad, he'll fuck you up.

all neiler 

When one has massive amounts of work to do and waits till midnight to begin but then passes out halfway through, usually 3 or 4 am. Almost an all-nighter, but does not make it.

I pulled an all neiler for my english paper.

I needed some sleep, so instead I pulled an all neiler
