The line comes from Fire Emblem Echoes: Shadows of Valentia, the 2017 Nintendo 3DS remake of Fire Emblem Gaiden. Like the rest of the game it is fully voiced, which helped short reaction lines circulate outside the game as standalone clips. Players shared the quote on soundboards and in edits because its wording fits far beyond its original scene, applying to any joke, insult or prediction that turns out to be correct. Its formal phrasing also makes it stand out from more casual reaction sounds.
