How it's used
This is a highly informal and slightly derogatory slang term for police encounters. The term 龜 refers to the police, playing on the green color of old police uniforms or the slow, methodical nature of their checks. It is strictly for casual conversation among friends and should never be used when addressing an officer directly.
Examples
He was stopped and searched by the police last night, so he got home very late.
You didn't bring your ID card, be careful of getting stopped by the police.
