I read the following line on a certain book:
We've given the proverbial middle finger to the society
I know that proverbial means something to do with a proverb. But, how the middle finger has anything to do with proverbs? Isn't it more suitable to say:
We've given the figurative/metaphoric middle finger to the society?
Is there any famous proverb that involves giving the middle finger to the society in English.
Sorry about the language, but I really need to know.
