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".
