Spoiler Police 

People who go to desperate measures to avoid spoilers. Even if its a game/show/movie they already seen, they go insane when they see one tiny spoiler.

Gamer A: Did you hear about (game)?
Gamer B: Yeah, (character) dies, its sad.
Spoiler Police: SHUT UP! NO SPOILERS IN HERE!

spoiler slut 

A person who can't wait until an episode of a show airs to find out everything they can about it, and goes looking or asking for "spoilers" about the episode.

"Oh, man, did you see the preview of the 'Smallville' finale?"
"Yeah, I heard Chloe dies in that episode."
"What?!!! No way! Tell me more."
"You're such a spoiler slut."

Spoiler Etiquette

The time at which it is deemed acceptable for a movie/TV show plot to be discussed in your group of friends without being worried about ruining it for others, because fans of the film/episode would have watched it as soon as they were able to.

Movies - 1 week. Fans of the film would be able to attend a screening within one week of the films release.

TV shows - 1 day. The true lovers of this show will live stream it or record/TiVo the episode and watch it as soon as possible.

"Dude, why are you so mad that I talked about who died in Game of Thrones this week? The show aired on Wednesday and it's Saturday. Spoiler etiquette has been upheld!"

Spoiler plate 

This is a custom license plate for your car which the owner decides will say or spell.

The spoiler plates on the back of that car don't make any sense at all.
