The greatest movie of all time. There's so much body dismembering and excessive amounts of blood that it keeps you entertained throughout the movie.

Guy 1: Man, i saw Ninja Assassin the other day

Guy 2: Oh me too, there's so much blood i could have sworn i was watching a documentary on PMS!

Guy 1: o.O

ninja assassin 

In roleplaying games (especially ones not centred around physical conflict), a character who has been designed expressly to be extremely powerful in a fight and/or extremely stealthy.
The term is frequently used sarcastically, as creating such a character is often a sign that the person doing so still thinks he's playing D&D.

Did you see the new guy's character? He's a complete ninja assassin.
