H is a number 

A joke that most people don't get that's mostly used in purposes of baiting switch.

H Is A Number (or H-roll) first became a thing on August 13th, 2020 when some users had a general discussion on discord, some people were talking about age restrictions.

"Users under 13 cannot use discord" someone said.

Of course, people were joking about someone being underaged after that message. Another user replied with:

"Age is a number, not a problem"

And that's where the joke basically began...

Some hours later, a user by the name of "undR/H cancer not allowed" posted a morse code that once translated said this:

"H is a number, just got H-rolled"
(There's numerous ones but this one is the most well known message)

From then on, the joke "H is a number" is not just used to warn moderators that users under 13 are on their discord server, but it's also used for morse code conversations, ending with the phrase "H is a number" or "-H" as a joke at the end of the message. Of course it's not just used on discord only, since it's a meme, it can spread from person to person.

Hey, did you know that H is a number ?

resident registration number 

That stupid annoying crap that South Korean websites force users to enter when signing up for an account, whether it be for MMOs or other entertainment sites. This means consumption of those sites is strictly stuck in South Korea. The government forces this because they are very data sensitive and video game addiction is a major issue in the country.

This atrocity of humanity infamously encourages identity fraud where outsiders buy resident registration numbers in an attempt to get access to those sites. If you try doing so and you get caught, you can end up being fined $10,000 and sentenced to three years in prison.

Kyle: Hey, do you know any South Korean MMOs that don't require a resident registration number to play?
Chris: Well, most of Nexon's game's that are available worldwide don't.

Once the trick has been initiated, NOTHING can stop it. Not even a shotty not.
