The term 5/15 has a correlation much like that of 4/20. 4/20 is a term originated from a group of teenagers at San Rafael High School in San Rafael, California, United States in 1971.The teens would meet after school at 4:20 p.m. to smoke marijuana at the Louis Pasteur statue and the day is nationally known as national pot smokers day. A small town called Tell City High School, in Indiana began this tradition a few years back. There was nothing to do in the small suburban town so when the athletic practice would get out (at 5:00) or if there was a football game or basketball game that started at 5:30 all the jocks and the cool kids would go to the parking lot at 5:15 to drink alcohol. The same group of kids and other followers of this counter cultural type practice that arent interested in smoking weed on 4/20 now get together on 5/15 (May 15) and get plastered.

Rule 15.5 

If a video game exists, there is Thomas the Tank engine of it in some form. Whether it be through the game's own features, mods, or just artwork, you are bound to find something related to Thomas the Tank engine in any game.
>"Seriously, this game just came out and already there is a mod that adds Thomas the Tank Engine?"
>"Yeah dude, that's Rule 15.5 of gaming"
Rule 15.5 by GrimoireOfMarisa November 21, 2019
A code for what will happen if you so choose to indulge in statutory rape, aka sex with someone under the age of consent. A breakdown of the code is

5= 5 minutes in bed

10= 10 hours/minutes in court (because it won't take a judge or jury long to convict your ass)

15= 15 years in a magic castle where people will gang rape and beat the living god out of you because you're a convicted pedophile.
Dumbass: Yo, bro I's gonna go fuck this bitch over there.

Guy with some intelligence: Dude, she's 15, you're 25

Dumbass: So bro she's just a ho bro?

Guy with some intelligence: 5-10-15 dumbass

For some reason the government looks at sex as some kind of contract, and you cant agree to a contract if your under their arbitrary age. So if the girl is 17 and your 18, just wait, because if she gets pregnant and her daddy finds out it's yours, he'd probably love to 5-10-15 your ass. On the other hand if your 25 and want to screw a 17 year old, eat shit pedophile.

endwarfins

The rush of neurotransmitters and neuropeptides triggered specifically by watching the Seven Dwarfs march home singing "Heigh-Ho" — that particular high of pickaxes, whistling while you work, and communal domestic bliss in a cottage built for men half your height.
I only meant to watch the Heigh-Ho scene for the endwarfins, and then it was two hours later and I'd watched the whole movie.

Endwarfins aren't just a Snow White thing — I get the same hit off the Lollipop Guild in Oz.
