What is what does love you long time mean?

The phrase "love you long time" gained widespread recognition from the 1987 film Full Metal Jacket, where it was used by a Vietnamese sex worker speaking to American soldiers. The line became memorable due to its broken English and has since been used in various contexts, often humorously or ironically, to convey an exaggerated or insincere expression of affection or commitment.

In contemporary usage, it can sometimes carry connotations that are considered offensive or stereotypical due to its origins and the way it caricatures Asian dialects and accents. It's important to consider the context and audience when using the phrase, as it might not always be well-received.
