Simlish is the fictional language spoken by characters in The Sims, the life simulation series created by Will Wright and developed by Maxis, first released in 2000. Its made up syllables and exaggerated intonation were designed to convey emotion without real words, so short interjections like this oho travel easily between games, clips and edits. As gameplay videos and soundboards spread online, players began isolating these tiny reactions for reuse elsewhere, and the sound remains popular because its meaning is clear from tone alone.
