SuS

Even though the word sus is now used in relation to among us, this word (and other similar like SoS, SeS, SaS, SiS, LeL,...) was first created in YTPs (YouTube poop), precisely by KroboProductions (now on yt as Dikekike). In fact this term refers to "a video editing technique by taking a word that either starts with or ends with an S and playing it forward then backwards, thus creating a SuS sound" (cit. knowyourmeme.com/memes/sus).

"it's the SuS of life" (cit. www.youtube.com/watch?v=A6Rh-oy0SDk)
