No, I'm not joking. This ridiculous language for a code golf actually beats some of the more normal languages.

wagwan my slime
man say"Hello, World!"
chat wit u later fam

My first RoadLang answer! And probably the first one on this site!

Removing any of the words says "Aight the lad's lost the plot", so I think this is the most minimal answer I can get here.

Thanks to Quintec for patching string parsing so that this works.

"Hello, World!".say

Explanation

First second answer of the.. entire site, actually. Nothing special. I don't think this can go shorter, but this is Raku, who actually knows. I made this post to (possibly) try and set a precedent for what a answer should look like. Obv you don't have to explain it, but it's nice.

Basically just keeps replacing the current cell value with the ASCII value of whatever character in "Hello, World!" its printing and moving on. I might add a more detailed explanation later (or maybe someone else can, if they feel like it).
