原谅我不是逗比
[yuán liàng wŏ bù shì dòu bĭ]
'Forgive Me for Not Being Silly,' where 'Silly' also means clown-like or goofy. Often, it reflects the individual wanting to express a more mature or serious side but being playful and self-deprecating at the same time. It can imply a request for others to see beyond their humorous exterior.
