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.
