The masturbating ninja technique 

When a gentlemen decides to enter the masturbatory stage of his day, he may decide to deploy the homo sapien style (standing up) only to realize his t-shirt drops down into penile range. To avoid ejaculate or any lubratory means being transferred onto ones personnel, the ninja technique is engaged by whipping the front flap of the t-shirt over the head to create a warm, stylish, and protective measure against the army of unbelievable stickiness.

Policeman 1: "We found this fine young lad frozen to death here in the arctic tundra'.
Policeman 2: "It looks like he's been out here for weeks and missed the warm soothing touch of a woman, and decided to literally take matters into his own hands".
Policeman 1: "Correctomundo. If only he had a mentor to teach him the ways of the masturbating ninja technique, he might have pulled through".
Policeman 2: "Hey! Yeah that's true. If only he kept his shirt flipped over his head with his shoulders covered instead of taking it completely off, he'd still be here today".
Policeman 1: "Poor, poor, uninformed bastard".

Cheeks 

An Irish phrase meaning shit, derived from ass
(Not to be confused with the literal description of one's buttocks)

"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."
