the sums 

A joke name for the popular canadian pop-punk band Sum 41. Originated in the video to 'Still Waiting', where the executive (presumably) of their record label felt that 'Sum 41' was out and 'The Sums' was a better name for the quartet.
- The reason I called you guys in is that the number band thing is, out, ok?. What's in now is 'the'. The Vines, The Hives, The white stripes, this isn't new. Listen; 'The Sums'? Right?

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.
