wearing ones pants around the hips so that they sag down and bunch up around the ankles. Originally, this was a prison thing that signified that you were another prisoner's property, ie bitch. Punks were forced to wear their pants this way so it would be easier for their masters to pull their pants down and butt-fuck them. Somehow this became a 1990's fashion trend. I learned this from watching a TV special on prison life. The inmate who related the story was an elderly black gentleman who had been sentenced to life in prison and had been there for over fifty years. He marveled how such a mark of shame became a fashion statement. He said that younger inmates don't believe him when he tells them but swears it's the truth. I believed him. I also think they should let him out already, he's like 80 and I don't think he represents a threat to society.

Wearing your pants below your waist. It originally meant you were gay in prison (much research into finding and confirming that) but somehow became fashionable. It did not originally mean anything about a gang, which is an extremely common misconception. There is nothing cool about wearing your pants low.

Hip-hop and gangster cultural fashion: Wearing one's pants below the level of the waist, sometimes below the level of the buttocks, with one's boxer shorts showing. The style may date back to around 1989.

The origin of this originally young, urban, black style is unknown. A commonly accepted origin theory was that is was an outgrowth of prisons, where inmates' clothing was often too large and sometimes no belts were allowed.

It may be related to skateboard/snowboard fashion.

At least one scholar thinks there is a tie-in with African culture.

There is also some evidence that a male showing his underwear-covered buttocks in prison was, at one point, linked to a desire for sex, or a mark that a prisoner was "owned" by another prisoner, sexually. Whether this kind of showing one's buttocks has any relation to sagging is unclear.

Some areas have begun to outlaw this style recently (2011). Apparently the objection is the amount of underwear shown.

wearing ones pants below the waist to make pants baggier. This is seen as a "cool" way to wear pants, as seen by the number of rappers, skaters, rock stars, etc. that wear them. Usually a belt is not worn to reinforce sagging.

Wearing your pants in such a way that you shit your pant for a month and no one would know (exept for the smell). The resulting bloated backside would be similar that of a ghetto booty or bubble.
