馋酒成性嗜烟如命
[chán jiŭ chéng xìng shì yān rú mìng]
'Obsessed with Alcohol Indulgence and Hooked on Cigarettes Lifelessly' humorously (but perhaps critically) describes a strong affinity for alcohol and an addiction to smoking. It’s self-deprecating and candid about habits usually seen negatively, adding a dose of reality or confession style flair to the username.
