我没对你笑你别和我闹
[wŏ méi duì nĭ xiào nĭ bié hé wŏ nào]
'Don’t Mess With Me If I Haven’t Smiled At You' communicates boundary setting in social engagements or flirting. This implies a preference or rule: interactions should remain civil or casual unless there's a welcoming gesture first initiated by this person.
