spoilerize 

To remove spoilers from a description, especially a movie or TV summary, that might otherwise give away the ending or a plot twist to the unsuspecting reader. Can either be done by omitting spoiler content entirely, or by masking it on a web page in a way that the user has to click through or highlight text to read it.

You should spoilerize that movie review better, so people don't find out he was dead all along.

schrodinger's spoiler 

A schrodinger's spoiler is when a reference to a spoiler or joke is made but the context won't be realized or the content won't otherwise be spoiled until it's no longer a spoiler.

Me: I don't think he'll get the TPS report joke completely unless he's seen The Mandalorian Chapter 15.

Dumbass: Dude that's totally a spoiler.

Me: He won't get it until he's seen the episode so no, it's more of a schrodinger's spoiler.
