Not safe for neighbours means that you're listening to House Music and turn up the sub and bass to adequately buzzing levels. This of course is not safe for neighbours and will be sure to piss them off.

NSFN means you will get a knock on the door to turn that racket down, but at least you won't be able to hear the door!
Just listen to that bass, turn up to max volume NSFN!

Not Safe for North Dakota, who decided a fertilized egg has the same rights as a human. Thus an image of an egg being impregnated by sperm would be NSFND since it is, in their eyes, the same as a woman getting raped by many men.
Science: And here, in your health books, you can see that this little guy who has less brain cells than a fly, is impregnating the egg. Mind you, trillions upon trillions of these sperm are killed every time a man masturbates, and same goes for the unfertilized eggs, which are not living things. Hell you kill smarter things when you eat meat or step on bugs.
North Dakotan: HEY I CAN'T VIEW THIS! IT'S NSFND! AWW GEEZE, MIDGE!

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."
