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"

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.

pod person 

A person pretending to be something they aren't, or an impostor. This is inferred because of the old alien movies where alien pods appear on earth and the "pod people" dispose of the humans and slowly reproduce the bodies, pretending to be humans.
The pod person was pretending to be my father, but I knew that he was an alien when he acted differently than my father ever would have.

A dead drop is a location used to secretly pass items between two people, without requiring them to meet.

Spies have been known to use dead drops, using various techniques to hide the items and to signal that the drop has been made. Drug dealers use this as well.

A common place is to duct tape the item to the underside of a toilet cover in a public restroom.

A signal is sometimes used as well to indicate there is something to pickup, like a pile of stones in a certain formation. After checking the drop the signal is removed.
"The dead drop is the restroom toilet at the Gulf station at the corner of Commercial Ave. and Georges Rd."

No Surprises Wedding

A "No Surprises Wedding," or NSW, is a wedding invitation designation that tells attendees that there can be no unplanned announcements, engagements, events or speeches at the wedding - all actions must be pre-approved by the couple. Anyone who performs an unapproved "surprise" will be asked to leave the wedding early.

This designation comes from Reddit, where so many stories of bad wedding behavior indicated a need to communicate expectations for the wedding behavior of attendees.
You are cordially invited to the nuptials of Brian and Tom on October 31 at noon.

Please note that this wedding is child-free (under 10) and a No Surprises Wedding (NSW). Reach out to wedding planner Sami Smith to request approvals or exceptions; please note that exceptions will be rare. Limited child care for under-10s will be available. All approvals will be noted and included in planning. Unapproved, or surprise exceptions, will result in guests being asked to leave.

EBK stands for "Elite Ball Knowledge." 1 In internet slang, "ball knowledge" originally referred to a deep understanding of football/soccer or basketball, but it has evolved into a broader term for having a highly sophisticated, deep, or niche understanding of any specific topic (such as music, movies, or subcultures).
Person A: "That scene was a direct homage to an unreleased 1982 Japanese indie film."
Person B: "Wow, EBK."
