我总是对着镜头犯花痴
[wŏ zŏng shì duì zhe jìng tóu fàn huā chī]
Means 'I always turn into a flower fanatic in front of the camera'. It humorously expresses someone's tendency to act silly, overly excited, or obsessed (often referring to adoring celebrities), especially when taking photos or videos of themselves.
