"Not For British School Kids"

Uses:
1. In place of a swear word
2. Describing a topic that is obscene, disgusting, or in general "not for kids"

Origin: Circa 1998
At the snopes.com message board, an obviously irate woman posted saying the other posters should watch their language, because there were British school children reading the message board. From then on, as a joke, the other snopesters started using NFBSK in place of swear words or in the subject lines of topics that might not be suitable for children (or the squeamish).
1. I moved one Jenga block and the whole NFBSKing thing fell down!
2. I'll tell you about my surgery, but I must warn you, it might get a little NFBSK.

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!
