A ponderous tome, containing information in an encrypted form of english. Supposedly teaches how to do math, but incomprehensible to anyone who cannot already do math (See catch 22). Often, the number of Greek letters and obscure symbols found within outnumber the actual english words. Enjoyed by no one. Any exceptions lie.
After hours of studying his math book, he understood no math.

A Pi-Free Math Book 

The mathematical equivalent of a meeting-free day or passport-less travel. When the sight of the symbol π is enough to trigger panic or paranoia among billions of folks worldwide, who think they weren’t born or blessed with the “math gene.”
Just as a math book without equations or formulas could raise the sales figures by a few folds, a pi-free math book could give thousands of math-anxious folks more confidence in picking up a pop math book without feeling unduly stressed.

Singapore Math Books

Math titles that marry decent quality with affordability—authors must be racially, religiously, and sexually sensitive, while the Ministry of Education (MOE) controls the price of the books.
Because Singapore math books cost a fraction of their American counterparts, US distributors have been importing them for homeschoolers, who think they're getting value-for-money textbooks—a number of them might even mistake Singapore for a city in China.

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.
