滚滚滚滚你爸的海枯石烂去去去去你妈的天长地久
[gŭn gŭn gŭn gŭn nĭ bà de hăi kū shí làn qù qù qù qù nĭ mā de tiān zhăng dì jiŭ]
An expressive, colloquial and somewhat crude saying that essentially means getting over someone/something completely, not taking them/it seriously. Though rather impolite, it expresses an attitude of letting go and refusing to linger emotionally.
