别拿你的脏嘴来吻我
[bié ná nĭ de zàng zuĭ lái wĕn wŏ]
"Don't kiss me with your filthy mouth" is self-explanatory yet quite harsh sounding. This indicates a defensive stance taken by its owner, rejecting unwelcome advances and emphasizing the importance of respecting personal boundaries in physical closeness. One would use this nickname showing resistance to being violated.
