話人無聊應該點講??

idiotic, senseless, silly, moronic

In engllish, there is no literal or exact word matching the meaning of one chinese word's exact sense. We can only use the most appropriate and accurate word to express and describle the actual meaning of our own.
In this case, you would say: you are silly or don't be silly or that 's annoying
Remember don't use a word that is confusing and complex, always stick to the simplest form

you is so boring = 你好無聊

you are nonsense! = 胡說!廢話!
