病人已经是强迫症晚期
[bìng rén yĭ jīng shì qiáng pò zhèng wăn qī]
The phrase suggests that the person has an obsession or compulsion about certain things or behaviors, implying a humorous exaggeration of their particular habit or preference as being uncontrollable. In modern context, 'OCD' can mean a very neat and organized personality.
