noun
Originally a short comic play performed between acts of traditional theater; now often used figuratively for any absurd or ridiculous situation, especially a poorly staged deception or a farcical event.

喜劇 is a general term for comedy or comic drama, while 茶番劇 specifically implies low, farcical, or absurd comedy.
From 茶番 (ちゃばん, a comic interlude performer in traditional theater) + 劇 (げき, play). The exact origin of 茶番 is uncertain, but it likely refers to a low-ranking servant or jester figure in Edo-period theater.
