saas-bahu

(India) A mother-in-law, especially the mother of the groom, who lives with the married couple.

An Indian internet slang term — specifically a phonetic respelling of 'sir' as pronounced with a strong South Indian accent, particularly associated with Tamil Nadu. It went from a genuine honorific to a beloved meme staple, used to mock over-the-top deference, corporate brown-nosing, or the exaggerated politeness of certain customer-service interactions. Now it's deployed with pure affection by South Indians and everyone familiar with the meme ecosystem around it.

An Indian person.

(derogatory, chiefly, social media) an archetypical Indian bureaucrat, perceived as being corrupt, lazy or arrogant.

A romantic partner whose behavior raises consistent red flags but who has not yet been fully caught or confronted — someone you're technically with but whose stories don't quite add up, whose phone goes face-down too fast, and whose explanations require a flow chart to follow. The sus bae keeps you on edge not because you have proof of anything but because the pattern of small weird things is becoming a statistical improbability. Friends say 'leave'; you say 'there might be an explanation'; both of you are right.
