Gremlins is the 1984 horror comedy film directed by Joe Dante, about small creatures that multiply and cause chaos after their care rules are broken. Clips reacting to the film circulate online as shorthand for stunned disbelief, in the same family as oh my god, wow reaction sounds. This version is used less as film commentary and more as a reusable reaction, pasted over gaming fails, pet chaos, and other moments where something small escalates into total mayhem very quickly.
