Mother Sigma

Works as a substitute for mother fucker but is seen as more volatile and should only be used when wanting to hurt someone's feelings to the fullest extent, seen as great disrespect when used and definitely shouldn't be used in your day-to-day life

Jake: Bro I hate you mother sigma
Everyone else: Gasps at such a cruel expression

Some stupid TikTok thing where an A.I. voice clip of Squidward saying "Erm, What the Sigma" is used in brainrot videos.

Person: "I sure as heck hope A.I. doesn't take over the world in a few years"
