饮鸩止渴
[yĭn zhèn zhĭ kĕ]
Literally means to drink poison to quench thirst (from Chinese idiom: “饮鸩止渴 yǐn zhèn zhǐ kě”), which implies a person is willing to take harmful actions for temporary relief or benefit despite the serious future consequences. This may also suggest the user knows about their own self-destructive habit and uses it metaphorically in daily usage.
