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!"

Word of the Day on October 28, 2026
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
You didn't get any napkins with your takeout pork fried rice? Womp womp.

Surf Dracula Syndrome 

A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.

For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
I watched "Smallville" on Netflix the other day. Dude, it was ten seasons of filler before he finally flew! Major Surf Dracula Syndrome!
