Scrawls on public bathroom walls are a bit different and fall into a category of their own, a phenomenon that has been the subject of entire academic studies. Officially called “latrinalia,” writing on bathroom walls is something that psychologists have suggested we do because of the potential to express things that may be inappropriate without being suspected, as it’s being done behind closed doors in a space where people usually keep to themselves.

Such bathroom art is almost like posting on online forums. And much like the modern anonymous comments section, the content often tends toward crude and inflammatory, but this list shows that there are some well-wishers who want to brighten their captive audience’s day with cute messages.

Some people have even used the stereotypical kind of vandalism that city councils hate for material good. Last year saw an epidemic of Brits forcing their local authorities to prioritize road repairs by painting every uninventive tagger's favorite body part over the offending potholes.

In 2015, one anonymous chaotic good character became infamous for the practice in Manchester, calling himself Wanksy, and apparently the approach that he pioneered has been repeated with success elsewhere. Locals can complain about this method all they want, but they can’t say it doesn't get the job done.
