Sneaky Ninja 

Have a friend hide in your closet before you bring a girl back. Turn off the lights before you start having sex with her. Before you finish, have your friend quietly come out of the closet and replace you. Then turn on the lights and yell 'SNEAKY NINJA BITCH!'

'dude, last night I totally sneaky ninja'd that bitch.'

'no way! what'd she do?'

'strangely, she was into it... she's fuckin wild man.'

ninja 

Practitioner of a martial art developed as a means of countering Samurai military power and monopoly of single-edged swords. Erroneously thought by many to have evolved in Japan. Revealed in "Batman Begins" to actually be practiced way up in the mountains in Tibet, thus rendering Ninjas safe from any surprise attacks from the Samurai, who did not live in China.

Hello Bruce Wayne! I am an Irish Ninja living in the Himalayas, and I am here to teach you to be Batman!

Social Ninja 

Somone who avoids contact, or in any way of communication, usually very arrogant and stuck up. No matter what evidence is put in front of them (when theyre actually talking) they will just snicker in your face and say that "my word is the law of nature" and try to use your words against you. Usually theyre worthless. Very smart but with no common sense or manners. Friends are scarce.

Zach is a social ninja, and a nerd
