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.
