"Funny Aneurysm" Moment is when events, either external or within a series, turn a joke into something disturbing, upsetting, or at the very least really uncomfortable. Harsher in Hindsight is when a tragic and serious event is even worse later.
This is the opposite. It's when a later event, such as a current event or something that happened in the series, is funnier than it originally was. This is what your literature teacher would call "Life imitating Art". There's a decent list in this College Humor feature and another one in this Cracked.com feature.note
Note this is not merely something that seemingly predicts something else. For example, black US presidents in fictions are not this trope. A black US president in fiction who has an Embarrassing Middle Name would be.
Additionally, "hilarious" doesn't just mean "BLAH-HAH-HAH! gut-busting," either. If you go by the word's original definition, it can mean "amusing" or "charming" as well. So any belated lighthearted coincidence would fit under this trope.
Contrast "Funny Aneurysm" Moment (when something that was once amusing or awesome is now tinged with tragedy thanks to a Real Life or in-story tragedy), Dude, Not Funny! (when something is considered in bad taste to mock or even mention, no matter what the circumstance), Hilarious in Flashback (where a glimpse of the characters' past contrasts amusingly with their established personalities and situation), Harsher in Hindsight (when something dramatic or depressing is now worse due to a Real Life or in-story tragedy), Unintentional Period Piece (in the cases where a work that was current when made almost only makes jokes that no current reader can understand) and Two Decades Behind (when the writer thought it was current but wasn't), and finally If It Was Funny the First Time... (in cases where a Running Gag is overused or a joke is only funny once). A "dated reference" is when a single joke (or only a handful) in a series is no longer funny because nobody alive remembers why it was funny, but is Not a Trope as it is mostly covered by Unintentional Period Piece and Two Decades Behind.
Unfortunately, there is no trope or term for when something that was funny is remembered to have been so by people still alive, but is no longer funny because of a later event that simply invalidates the joke - which now falls flat - rather than in a way that is disturbing (in other words, not a "Funny Aneurysm" Moment but a similar concept in which a specific event causes a normal joke to unexpectedly and instantly become a dated referencenote . Yes, this does happen, ranging in obscurity from "Pirates?" "...of the Carribean!" "Somebody's been to Disneyland too many times!" from Captain Ron, a relatively obscure 1992 family comedy film (thus predating the reference which would currently be considered funny), to "You're Fired!" "Money, Money, money, money..." after the 2016 US Presidential Election in uses of the meme that aren't Harsher in Hindsight or a "Funny Aneurysm" Moment.
