你用和别人缠绵的嘴说爱我
[nĭ yòng hé bié rén chán mián de zuĭ shuō ài wŏ]
The net name directly translates into using the same mouth that's affectionate/intimate with others to say 'I love you' to me. This reflects skepticism or frustration over genuine emotions expressed verbally due to previous experiences where those words seemed insincere or inconsistent with actual behavior.
