Define Express Delivery Meaning

An intentional and malicious act taking place in a public restroom. The offender enters a restroom to take a shit in a stall next to an occupied stall or stalls containing an unknown victim or victims. The offender defecates quickly and wipes, but refrains from flushing the fresh feces down the toilet. The foul odor from the shit fills the stall and adjacent stalls, and eventually the entire restroom. The offender must quickly exit the restroom without being seen before the victims, who are still in the act of having a bowel movement, have the opportunity to escape the fumes.
