Long time no see

[Justin Bieber]

[Long time no see] means: I have not seen you for a long time.

It is a grammatically comical greeting with English words organized by Chinese grammar. In Chinese there is an everyday greeting Hao [jiu] mei [jian] which corresponds with [long time no see], literally word by word. It is said that Long time no see was first used by Chinese-Americans.

[Gregory]

said when you meet someone who you havent seen for a long period of time
