The Vietnamese word "lẳng lơ" is an adjective used to describe a person, usually a woman, who behaves in a flirtatious, seductive, or immoral manner. It can imply a lack of modesty or propriety in one's behavior.
In more advanced discussions, "lẳng lơ" can also refer to behavior that is perceived as unrefined or lacking in moral integrity. It can be used to describe not just women, but can also metaphorically apply to situations or actions that are seen as indecent.
While the primary meaning of "lẳng lơ" focuses on flirtation and immorality, it can also be used more broadly to describe someone who is overly playful or lacks seriousness in certain contexts. However, this broader usage is less common.
When using "lẳng lơ," be cautious about the implications, as it carries a strong negative connotation.
