原谅我这一生放荡不羁的嘴
[yuán liàng wŏ zhè yī shēng fàng dàng bù jī de zuĭ]
Can be interpreted as 'Forgive my irreverent mouth throughout my life', hinting a lifetime marked by impolite speech or words deemed improper, perhaps even rebellious and unconventional. The speaker acknowledges past verbal misconduct, whether real or feigned, asking forgiveness while potentially also showing reluctance or irony, a mixture of defiance and remorse.
