Theoretical bug 

When you discover that your code is not giving the right results, not because there is any bug in your program, but because there is a bug in the theory on which it is based.

Theoretical bugs are rare but more common than thought. When you find one, your perception of the world improves quantically.

A more day to day example, it is when you realize something you never saw before, not because it was not there, but because your mental model of the world didn't include it.

JC: I've been trying to find the bug in this program all night, but its looks perfect. Don't know why sometimes is producing weird results.
Guru: Its time to chase some Theoretical bugs.

case 2:

Linux_user: The problem with microsoft is not that they produced bad programs, but they copypasted so much software from other people, that the outcome was a walking Theoretical bug. At some much extent that, when it crashed it means it was really working.

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.

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!
