LTNS meaning in Internet Slang ?

Answer: What is Long time no see mean?

"Long time no see" is an English expression used as an informal greeting by people who have not seen each other for an extended period.

The phrase is often portrayed as originating in Chinese pidgin English. It may have been coined at one point based on the Cantonese phrase "好耐冇見" (Jyutping: hou2 noi6 mou5 gin3), or the Mandarin phrase "好久不見", both of which yield the exact expression "long time no see" when translated directly into English.

Some also believe the term may have been coined by native English speakers, in imitation of Native American pidgin in cinematic portrayals. Over the following decades, the expression has since been embraced and used around the world.
