In Germany there is “Max Mustermann”, which basically translates to Max Template-man. It’s the default German name used for templates of official documents like passports and such.

In my country (Spanish speaking) we say “Fulano de tal” Fulano is kinda like a template name nobody really is named like that. “De tal” really means something like “from somewhere”.

We dont out it on the graves, but we use it as slang for situations where we need to refer to someone generic like “imagine a fulano de tal doing xxxxxxxxxxx”.

There are other names like Zutano, Mengano, etc.

Edit: My mom sometimes uses “Miguel Perez”. Those 2 are very common first and last names.

In US legal cases, “John Doe”, “Jane Roe”, and similar names are used for pseudonymized legal parties.

For instance, the plaintiff in the famous abortion case Roe v. Wade was one Norma McCorvey, identified as “Jane Roe”.

A group of unidentified people appearing as plaintiffs or defendants may be called a group of “Does”, from the name John Doe.

The words doe and roe both refer to deer, which are common wild animals in North America — and as wild animals, represent an arbitrary unspecified person. A doe is a female deer; and while “roe” can also mean fish eggs, roe deer is a common European species of deer.

Denmark -

Brian <- A name, but also a slur for people considered ‘hillbilly’. Very frequently used against people who drive cheap tuner hatchbacks. Said cars can be referred to as Brian Cars.

Peter Jensen <- Also a name, but it’s become notorious in Jutland because it feels like everyone is immediately related to someone with this exact first and last name.

Germany uses Max/Erika Mustermann – literally Sampleman. It’s used for example on official sample pictures of our IDs. Some authorities in erlin have startet to use the gender neutral name Manu Mustermann.

We have the phrase ‘every Tom, Dick and Harry’ which is like that (UK)

If we’re talking about a generic person it’s usually Mr/s Smith or Mr/s Jones (near Wales)

In the Netherlands there’s “Jan Modaal”, modaal (modal) referring the most commonly occurring value in or peak of a distribution. This name is used often when representing the experience of the most average Dutchman.

It’s especially often used in financial discussions and journalism, like “owning a house is getting further out of reach for Jan Modaal.”

In the Philippines, it’s Juan and Maria dela Cruz, although those have fallen out of use due to the popularity of Western (aka US) culture. Interesting reading about every country’s own names for their everyman.

In Vietnam, I think it’s just most names 😂. Anh Nguyen is probably a good example. Most Vietnamese have the last name Nguyen. The national naming conventions rival that of religious families in the west. Think, Matthew, Mark, Luke, and John. Anh, An, Thanh, and Minh. Women are the same, but named after things considered beautiful, Tuyet, Hong, Pham, Van.

Funny enough, many names aren’t always gendered, so I’ve met a decent amount of couples with the same first and last names. An Thi Nguyen, and An Van Nguyen is a couple that comes to mind. I dont have to worry about doxxing, since I bet that exists over 1000x here.

Flemish talking part of Belgium it is Jan Janssen

In the UK for a random guy it’s usually Joe Bloggs.

In Norway we have the stereotypical Norwegians “Ola Nordmann” and “Kari Nordmann”. Ola and Kari were quite common names a couple generations ago (not so common now). “Nordmann” literally translates to “Norwegian [person]”, but is also a not-too-uncommon last name.

We typically talk about them if we’re describing something or some situation and what the stereotypical Norwegian would do/think.

In the UK it is Joe Bloggs

In Norway we have “Ola Nordmann” and “Kari Nordmann”. Ola and Kari are pretty common and generic names. Nordmann literally means Norwegian, but can also be used as a last name.
