Meaning:
“正” means “right,” and “点” means “time.” This phrase in Mandarin means “right on time” or “punctual,” as seen in the sentence “The train is always punctual.” (火车总是正点到达。) However, more and more people have accepted another meaning for the term, which originated from Cantonese dialect. When people say a person or a thing is “正点,” or simply “正,” they mean the person or thing referred to is “very cute or exceptionally good.”
Example:
A: 我昨天在外面吃饭，遇见小马和他的女朋友。
Wǒ zuótiān zài wàimiàn chīfàn，yùjiàn xiǎomǎ hé tā de nǚpéngyǒu。
I met Xiaoma and his girlfriend when dining out yesterday.
B: 听说那个女生很能干，是个设计师。
Tīngshuō nàge nǚshēng hěn nénggàn，shì ge shèjìshī。
I’ve heard the girl is a designer and very capable.
A: 还很正点哦。
