装逼大咖梦射天
[zhuāng bī dà kā mèng shè tiān]
Breaking down this peculiar nickname, 'a big shot at faking it and dreaming high', it seems like a sarcastic or humorous way of mocking someone who pretends or exaggerates. The words '射天', literally meaning 'shooting at the sky', can mean 'aiming for the unattainable dream' or 'daydreaming wildly'. Altogether, it might describe an attitude that tends to fantasize or exaggerate oneself unrealistically, but in a rather self-deprecatingly funny manner.
