when a female wants to take out anger on a man during sex so she injures him somehow
I am so pissed at him, I am going to vaninja him.
An ninja-esque attack, using the "power of the poon"; A female will utilize this sneak attack on a man to overpower him to her advantage, to obtain her female desires (i.e. sex, money, clothes, etc.). Only by mastering this skill can a female be known as... a VANINJA!
TOOLs are usually susceptible and very easy targets for the VANINJA.
Some clues of the VANINJA:
-Low cut shirt that exposes hella cleavage
-Always rubbing on dudes
-Always hanging on dudes
-Wears tight clothes to show-off curves
-Exclaims how DRUNK she is
