How it's used
This expression is a highly offensive, vulgar intensification of 黐線. It functions as an adjective to describe someone behaving erratically or irrationally, but it carries a strong aggressive or derogatory tone that can easily escalate a conflict. Avoid using it in any professional, formal, or polite social setting as it is considered extremely rude.
Examples
Why are you acting fucking crazy?
He is fucking crazy, he speaks without thinking at all.

Common phrases
fucking crazy behavior
Common mistake
Learners often mistake it for a generic intensifier like 勁 or 爆. Using it to describe a situation or object that is simply 'cool' or 'amazing' is incorrect and will sound bizarre or unintentionally insulting to native speakers.
