如果我是深海你愿意跳吗
[rú guŏ wŏ shì shēn hăi nĭ yuàn yì tiào ma]
This translates to 'If I were the deep sea, would you jump?' suggesting an invitation or challenge to follow someone no matter what, even if the decision is risky or irrational, similar to 'jumping into the unknown' with a close friend or romantic interest. It implies dedication or unconditional trust between the users of the nickname and its intended audience.
