What phrases are for “noun + anonymous”?
I’ve already found
- smokers anonymous
- alcoholics anonymous
Are they always used for places where people go to quit using something, or have other meanings?
Those are both names of organizations. There are many organizations with names that follow that pattern. The first was Alcoholics Anonymous (AA), which is an organization to help alcoholics quit (and stay off of) alcohol. Other self-help organizations probably used similar names to draw parallels with AA. Many of these also use much of the same philosophy or methods, such as the “Twelve Steps”. There’s a list of such groups on this Wikipedia page. Some other examples from that page:
- Narcotics Anonymous
- Heroin Anonymous
- Overeaters Anonymous
- Workaholics Anonymous
- Online Gamers Anonymous
The phrase “alcoholics anonymous” literally means “anonymous alcoholics”, that is, “alcoholics who are anonymous”. In that phrase the adjective “anonymous” is used as a post-positive adjective. More information about these can be found in this Wikipedia page and this question.
