Positioning one's rectum directly onto the air intake of the victim's sleep apnea machine then farting, thereby pressurizing the evil stench before slamming it at a high rate of speed and pressure through the mask , nose and lungs of the unlucky victim.
After stealthily entering the abode of mine enemy with the intent and malice aforethought of delivering unto him a Chicago Sunroof, I looked upon him did see that he wore a sleep apnea mask. And this was bad, for a mask would surely be of hindrance to said delivery. And so I thought hastily and did contrive of a new delivery system. A system even more heinous than usual. And hence I did drop trou and placed my rectum directly upon the air intake of his sleep apnea machine and did unleash the darkness that dwells within my bowels, hence, inventing the Chicago Sunroof Turbo.
