不要脸那亲嘴
[bù yào liăn nèi qīn zuĭ]
It humorously means 'Kiss without face' where 'faceless' here conveys being shameless, daring, or bold, suggesting that one shouldn't be too shy about showing love or passion. However, it may contain some informal and humorous expressions which could be impolite depending on the context, so people should pay attention if you intend to use it.
