Derived from the abbreviation for “Student Union”, an S.U. is a smug, overprivileged young man from a middle class background who attended a private school before whatever costly further education he is currently in.
The sort of person Radio 1 wish their listeners were (rather than 40 year old forklift drivers), he will be studying a subject that is either ridiculously easy or meaningless, will never have had a job and will be financially reliant on his parents, whom he has already cost an astronomical amount.
Dressed in “Surf” fashions), these Prince Harry lookalikes (there are a disproportionate amount of pale ginger ones) blight cities bleating at the top of their lungs at their idiotic flatmates, buying pints of cider on their discount cards before sicking them up over halls of residence balconies.
At some point, borrowing Mum and Dad’s BMW just isn’t enough anymore and said parents will have to cough up for a “Gap Year” (despite the 20 or so he’s had already) wherever he’s heard there are prostitutes and weed. He will return from the trip to loudly tell everybody “What a real eye opener” the poverty he saw there was, despite there being districts not much better off a couple of miles from his parents’ £300,000 semi. In the unlikely event of finishing university, the S.U. will most likely take up work in Subway or Burger King but in some cases will swap his Che Guevara hoodie for a suit and go to work for an oil company or the government.
Geoff: "How did your gig go the other night, Jim?"

Jim: "Terrible. It was a student bar. Just a crowd of up their own arse S.U.'s!"

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.
