康忙北鼻戴上套
[kāng máng bĕi bí dài shàng tào]
This is a mix of playful language, '康忙' resembles an internet slang term 'kama' used as greeting, '北鼻' means baby, '戴上套' implies 'putting on protection,' possibly suggesting someone young being cautious, or it might be part of more nuanced, coded messaging among peers about responsible behavior or caution in various aspects of life.
