white hat 

Whitehat was a word previously used to mean that they may use the same way, however they are still the "good guys", and this is no different.

A whitehat hacker is someone who discovers (or attempts) exploits for good use. OpenBSD users/programmers often tend to be whitehats, although still a large number of FreeBSD users/programmers may be whitehats. In comparision I would say more OpenBSD users/programmers are whitehats.

Often when a whitehat finds an exploit, he often informs people as needed. IE: FreeBSD security mail list, OpenBSD security mail list.

At the same time I would assume more Linux users are blackhats due to the large number of pinhead users while most Windows users tend to know even less and primarily stay out of the "game" (this is no game, like blackhats think it is, you just wait until they come upon a server that does remote logging).

Blackhats are often pinheads who have nothing better to do then attack people to prove how "1337" they are.

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!
