This sound is tied to Boyfriend, the main character from Friday Night Funkin', the rhythm game that became widely popular online in 2021. Short vocal bits from the game spread through meme edits, animation clips and soundboard uploads because they are instantly recognizable and easy to drop into fast jokes. The laugh-like delivery stands out in the same way creators use a vine boom sound for emphasis, but with a more playful gaming tone. It remains popular with FNF fans and general reaction editors.
