the.com/madhouse

means A place or situation so chaotic and frantic that it feels like everyone in it has lost their minds.

from Literal before it was figurative — a 'madhouse' was originally a real institution for housing the mentally ill, a term in use since the 1600s. By the 1800s people had started using it loosely for any scene of noisy disorder, from a crowded household to a chaotic workplace, borrowing the image of inmates in uproar to describe ordinary bedlam (itself a word with the same trick: it was once a literal London asylum, Bethlem Hospital, before it became shorthand for chaos).
