爱情算个毛线
[ài qíng suàn gè máo xiàn]
A humorous and colloquial expression dismissing romantic notions outright, as '爱情算个毛线' translates literally into 'love counts as (fuzzy) thread?' which figuratively means 'Love is irrelevant.' In modern slang, this shows an indifferent or sarcastic attitude towards idealistic views of romance.
