Buttplosion 

When one attempts to release a short loud collection of methane gas, otherwise known as a fart, but releases a concentrated sphere of fecal matter into ones underwear. The collection of feces is usually leathery in texture, thus preventing excessive smearing, but it will stain.

The difference between a buttplosion and a shart is that it is more than possible for a shart to leak out quietly and discreetly. A buttplosion is incredibly sonorous, and cannot be done discreetly as it is a powerful, full-force anal gust that pushes the turd into the pants.

After a buttplosion it is imperative that the victim behave nonchalantly. It is a guarantee that the buttplosion was heard, but the crowd will only think the victim farted. Laugh at yourself, or pretend it wasn't you; but escape the premises as soon as possible, because the resulting anal waste will cause a foul odor to accumulate around the company you're keeping. Go to a safe and secure location, get some rubber gloves, and go through with the disgusting and sickening act of cleaning up the large bits of poop that has most assuredly spread copiously in your underwear. It is probably best that that the soiled underwear be permanently discarded after the incident, for there will undoubtedly be stains.
-Did you see Bill run out of here, what was that about?

-He farted and I think it was a buttplosion. He seemed pretty worried and scared.

-Poor bastard.

bumsplosion

The blast of diarrhea that occurs when one has been traveling in developing countries. The detonation is usually preceded by a series of tremors indicating the bumsplosion is imminent and it is time to run toward the closest safe blast zone. The bumsplosion can happen anywhere, however, and unless one has made it to a safe blast zone, they usually find themselves laying on their sides at the site of the bumsplosion for the aftershocks.
I tripped on a little girl while running down the beach, feeling the tremors, and I found myself on my side at the epicenter of the bumsplosion, my head on a sandcastle.

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."
