Young dudes refers pretty generally to someone who is outgoing, popular with girls and resides or has resided in Japan. The original and iconic young dude is an aspiring British writer named Kris Dunlop who first visited the peninsula in the late nineties. The website he then created: "Young Dudes Guide to Japan" covered drinking and entertainment venues in Japan and attracted a vast array of people who, like Kris, had experienced dating and the buzzing night life of Japan.

Common misconceptions include:
1) All young dudes are young. This is false. Some young dudes are as old as 45. Politely refered to as "older" young dudes, they are considered veterans among the community having lived in the "economic bubble" era of Japan when night clubs drew in large crowds and socializing reached its peak.
2) All young dudes are foreigners who came to Japan. That is also false. One notable member is a Japanese doctor who enjoys extra-marital relationships and offers invaluable advice to young dudes who have tied the knot.
1) "These young dudes were all over the place! They must have got every girl's phone number back there!"
2) It was too late - Naoko was already getting in a cab with two young dudes she had just met.

A Wolfstar (Remus Lupin/Sirius Black) fanfiction by MsKingBean89, often referred to as ATYD. It's been popular in the community since its release in 2017 on the AO3 platform but gained a mass popularity after it blew up on the Harry Potter side of TikTok. The plot is set in the 70s, during the Marauders' school years up until Halloween 1981. Incredibly slowburn, beautifully sad, charmingly written. The 188 chapter book was named after a Mott the Hoople song.
Person A: Fun fact, "All the young dudes" has a bigger word count than the Bible.
Person B: Sir, this is a Wendy's drive-thru

Person C: Hey, it's a full moon tonight, wanna go stargazing?
Person D: How dare you remind me, you little dipshit
Person C: Um.. sorry? ig I thought it would be fun. You know, we'd try to spot the Sirius star, the Regulus star, maybe even the Andromeda galaxy! I've heard that Sirius is particularly pretty next to a full moon...
Person D: Just murder me at this point, mofo. I *just* finished ATYD. I'M STILL NOT OKAY AND IT'S A FULL MOON LIFE ISN'T FAIR BECAUSE THEY DIDN'T GET A HAPPY ENDING. PISS OFF JK ROWLING
Person C: Sorry, sorry, nerd, didn't mean to hurt your feelings mate. Anyways, fancy a Mars bar?
Person D: Get. out.

Carriers of the news. They are a mean team and they can love.

Jokes aside, it's a song written by David Bowie but it's most famous version is of Mott the Hoople.
Oh, brother, you've guessed, I'm a dude, dad
All the young dudes (Hey, dudes!)
