"I have to see a man about a dog" or "I am in the john". The symbol explains to gentlemen which toilet door is the right one. Men spend more time in the bathroom than women, but they do not go there as often.
The men’s room emoji was introduced in 2010 and released as part of the Unicode 11.0 standard. This emoji can be found under the symbols
category. Because the men’s room emoji has been around for quite some time, it should display correctly in the majority of operating systems.
