你是猴子请来的逗逼吗
[nĭ shì hóu zi qĭng lái de dòu bī ma]
In this username, 你是 (nǐ shì) means 'you are', 猴子 (hóu zǐ) is 'monkey', 逗逼 (dòu bī) can be interpreted as ‘joker’ but with somewhat offensive connotations. It translates roughly to 'Are you the joker that was invited by the monkey?' - it's used to tease or scold someone for being silly, nonsensical, or foolish, similar to the English expression like 'What are you, a fool?' or more precisely like 'Who do you think you are kidding around like this?'
