Just a random meme fact:
There were two types of the meme word “sus”, the Among Us “sus” and the YTP “sus”.

The YTP type of “sus” 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.

The Among Us “sus” refers to an abbreviation for “suspicious” often used by players of the game Among Us when referring to those that are suspected of being an impostor.
