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.
