Nonjitsu 

The art of trying to act like a ninja, but infact failing due to non-ninja status. Ninjitsu + fail = Nonjitsu.

Chris preformed some of his Nonjitsu when he tried to climb that building and fell and broke his arm.

Notjitsu 

The dark art of Internet Fighting. The technique of claiming great feats of wealth, intelligence, strength, and sexual prowess on internet forums despite not actually having wealth, intelligence, strength, or sex. This is done to one up fellow internet users and claim a position of dominance over them and hopefully garner yourself much deserved attention.

You can bench 600 pounds eh? You must study Notjitsu.

Cheeks 

An Irish phrase meaning shit, derived from ass

"Did you hear the song Aylek$ dropped?"
"Hardly. Her music is absolute cheeks."

"My boyfriend say LaFlame is cheeks."
"Tell your boyfriend I said it's his mixtape that's cheeks."
