Toby Fox is the developer and composer behind the role playing game Undertale, released in 2015, where a small white Annoying Dog repeatedly interrupts serious moments with absurd appearances. Fans widely treat the dog as Fox's in game stand in, which is why short dog barks are shared under his name online. As Undertale clips and fan edits spread across video and soundboard platforms, the bark became shorthand for that same gag: a tiny dog derailing a scene for a fraction of a second before everything continues as normal.
