Lachsack

A Lachsack (German, literally "laugh sack") is a term for a person, typically male, who is easily amused or prone to excessive or inappropriate laughter. It carries a slightly pejorative connotation, implying that the person's amusement is shallow, unsophisticated, or even foolish. The term can also suggest a lack of seriousness or control. While not considered a particularly offensive insult, it implies a certain degree of ridicule. The word is not commonly used in formal settings and is more prevalent in colloquial speech.
