Ninja Goodbye 

After sex move. Once you finished fucking your girl and she's getting ready to leave, you karate chop her and then throw her out. This would be if she's talking too much or just getting annoying in general.

After we got down she was talking too much so I have her the ninja goodbye.

ninja dusting

Giving off a silent fart, grabbing it with your hand and then bringing your hand up in a ninja fashion and throwing your fingers open, unleashing the putrid stench.

Did you see that guy ninja dusting everyone? What a maniac.

ninja shower 

When you have a quiet shower by not turning the water pressure up to high so as to not wake up other residents within your residence who may be awoken by the sound of water flowing through pipes.

It was after midnight and everyone was asleep so in order to bathe thyself I enacted the ancient form and techniques of the ninja shower.
