North Korean Depth Charge
The act of someone taking a shit on another persons pillow by shitting in the pillow case so the victim doesn't see it leading to a smelly nights sleep because of the fat turd you left in their pillow case.
"During camp I pranked a counselor by leaving a north korean depth charge in his pillow case and thats why for the last 2 weeks of camp he was in a shitty mood."
