In old cartoons they used to put it on bottle labels to indicate that it was alcohol. I've never thought about the origins of it, I was just taught from an early age (through the cartoons) that it meant "bad stuff." Maybe if they put it on the labels of actual liquor I wouldn't have turned into an alcoholic. Or maybe not, because I did drink Molson XXX for a long time.

Hope this answers your question.
I could be wrong but I think in everyone's mind 'xxx' means triple x-rated porn. I guess that means it's harder than just single 'x' rated porn.
In the United States, the X-rating originally referred to a non-trademarked rating that indicated a film contained content unsuitable for minors such as extreme violence or explicit sex and thus was for adults only. When the MPAA film rating system was instituted in 1968 in the U.S., the X-rating was given to a film by the MPAA if submitted to them or, due to its non-trademarked status, it could be self-applied to a film by a distributor who knew beforehand that their film contained content unsuitable for minors. In the late 1960s to mid 1980s, several mainstream films were released with an X-rating such as Midnight Cowboy, A Clockwork Orange, and Last Tango in Paris. Because the X-rating was not trademarked, anybody could apply it to their films, including pornographers, which many began to do in the 1970s. As pornography began to become chic and more legally tolerated, pornographers placed an X-rating on their films to emphasize the adult nature of them. Some even started using multiple X's (i.e. XX, XXX, etc.) to give the impression that their film contained more graphic sexual content than the simple X-rating. In some cases, the X ratings were applied by reviewers or film scholars, e.g. William Rotsler, who wrote "The XXX-rating means hard-core, the XX-rating is for simulation, and an X-rating is for comparatively cool films."Nothing beyond the simple X-rating has ever been officially recognized by the MPAA.
xXx is used to denote the Straight Edge subculture of Punk Rock. It stands for: x - No Drugs (Includes Tobacco) x - No Alchohol x - No Casual Sex IT
