How it's used
This phrase is an extremely aggressive and vulgar way to dismiss someone's opinion or knowledge. It functions as a rhetorical question that implies the listener is completely ignorant or unqualified to speak on the subject. Because it contains the word 撚, it is highly offensive and should be avoided in any professional or polite social setting.
Examples
How the fuck would you know? Stop talking nonsense.
Common mistake
Learners often mistake this for a literal question about knowledge, but it is purely an insult. Using it with friends or strangers will almost certainly lead to a confrontation or physical fight.
