In current internet slang, **“圆头耄耋”** mainly refers to a kind of small cat—especially an orange tabby—with a very round head, a bad temper, and a stubborn, hard-to-tame personality. Here, **“耄耋”** does not carry its original meaning of referring to a person of very advanced age. Instead, it comes from a homophonic play on **“猫爹”** (“cat dad” / “boss cat”), and is used humorously to describe cats with this kind of domineering temperament.
