别用你那舔过B的嘴说爱我
[bié yòng nĭ nèi tiăn guò b de zuĭ shuō ài wŏ]
This nickname expresses intense dislike and rejection of hypocrisy or infidelity; 'Don't use your mouth that has kissed others (in an improper context) to say you love me', which indicates contempt for dishonest expressions of love and loyalty.
