他的口头禅就是没问题,不管什么事都这么说。Tā de kǒutóuchán jiù shì méi wèntí, bùguǎn shénme shì dōu zhème shuō.His catchphrase is no problem, and he says it whatever the matter.
老师有一句口头禅,那就是再来一遍。Lǎoshī yǒu yí jù kǒutóuchán, nà jiùshì zài lái yí biàn.The teacher has a pet phrase: once more.
我姐姐的口头禅是随便,每次问她吃什么都这样说。Wǒ jiějie de kǒutóuchán shì suíbiàn, měi cì wèn tā chī shénme dōu zhèyàng shuō.My sister's catchphrase is whatever; she says it every time I ask what she wants to eat.
