The Sims 4 is a life simulation game released in 2014, and its Sims express a wide range of emotions through voice, animation and sound rather than real-world language. Hysterical is one of the game's most extreme playful states, when laughter becomes loud, breathless and hard to stop. Clips of these emotion sounds have circulated in gameplay compilations and fan collections, where editors lift short moments for reuse. The laughter still works online because it is instantly recognisable, needs no subtitles and fits any over-the-top or absurd moment.
