爱情特么是精神鸦片
[ài qíng tè me shì jīng shén yā piàn]
This uses an expletive '特么' to emphasize the view: 'Love, dammit, is like opium for the mind'. It expresses extreme cynicism and dissatisfaction about love which gives momentary relief or happiness at the cost of health or sanity - much like a drug addiction.
