Stapy is a stapler character from the Battle for Dream Island universe, a long-running animated web series whose later seasons include Battle for BFDI and The Power of Two. Short vocal moments from the show are frequently clipped by fans and reused as reaction sounds in edits, memes and short videos. This one-second shout has travelled in that fan community because its meaning is obvious even without context. It fits alongside other panicked reaction clips such as Knuckles Oh No, which creators use for the same kind of sudden disaster moment.
