Zwh
Zwh is a colloquial term, primarily used in online communities and informal digital communication, to represent laughter. It is a phonetic abbreviation derived from the sound of laughter, similar to other internet slang terms like "lol" (laughing out loud) or "haha." The "zwh" sound is meant to evoke a more subdued or possibly amused chuckle rather than an overt, boisterous laugh. Its usage is common in text messages, social media posts, and online chat rooms where rapid and informal expression is preferred.
The exact origin of "zwh" is difficult to pinpoint, as is common with many internet slang terms
