Belligerent Pythagoreans 

Belligerent Pythagoreans — a term that makes you rejoice that disaffected DOMESTIC TERRORIST do poorly in school and generally speaking work alone.

The most effective way of using automatic and semiautomatic machine gunfire is by creating interlocking fields of fire to maximize body count. This can be easily done with two people but — THE MORE THE MAYHEM-ier. The effect of interlocking triangular fire is to literally drive individuals into another field of fire when fleeing.

Automatic weapons tend to “ride up” and the firing application has to be slightly different from a long weapon. At least that’s what YouTube videos say.

What do I know?
Instructor teaching faculty and staff during an active shooter preparedness class/drill:

“Now your worst nightmare is a team of Belligerent Pythagoreans with automatic weapons attacking your playground or your auditorium.”

Confused teacher:

Could you please translate “ Belligerent Pythagoreans” into “civilian”?

Instructor teaching faculty and staff during an active shooter preparedness class/drill:

Yes. What I mean by that is two DOMESTIC TERRORIST, who did well in school, who work together to create interlocking fields of fire, based on the theory of plane geometry.

Confused teacher:

So you’re saying that we’re — relatively speaking — safe, right?

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.
