胡说 (hú shuō) means to speak nonsense or to talk nonsense in English. It comes from the Chinese characters 胡 (hú), which means "random" or "reckless," and 说 (shuō), which means "to speak."

An example of using 胡说 in a sentence would be:

他在胡说，根本没有任何根据。 (Tā zài hú shuō, gēnběn méiyǒu rènhé gēnjù. - He's talking nonsense, with no basis at all.)

Another way to say "to talk nonsense" in English is to use the phrase "to talk gibberish." Here are some example sentences using "to talk gibberish":

She's always talking gibberish when she's drunk.

Don't listen to him, he's just talking gibberish.

The salesman pitch was full of gibberish and I couldn't understand a word.
