How it's used
This is a highly offensive and vulgar intensifier used to describe someone acting erratically or irrationally. It functions as a stronger, more aggressive version of 黐線. Because it contains a profanity, it should be strictly avoided in professional, formal, or polite social settings.
Examples
Are you fucking crazy? Why are you doing it like that?
He is always acting fucking crazy, it is really hard to stand.

Common mistake
Learners often mistake this for a simple adjective, but it is a strong expletive that can easily cause offense if used in the wrong company. It is not interchangeable with milder expressions like 傻傻地.
