The first bowel movement, often in several days, after going on a heroin binge. Opiates cause constipation, so junkies tend to get backed up for days or even a week or more, before their body finally forces a bowel movement. This is why they often hole up in a public bathroom for up to an hour, and there can be considerable tearing which contributes to the mess left behind.
