“Muah” and “Mwah” are both written sounds of a kiss, commonly used online to show love, affection, or friendliness.
A girl finishes chatting with her best friend and types, “Good night muah 💕” but then pauses. A thought hits her: is it spelled muah or mwah? She deletes it, retypes, and still feels unsure. Both look right, but something feels off.
This small confusion is very common in texting culture. In the age of social media, people use expressive words like muah / mwah to show emotion, affection, and closeness. But because these words are informal and not part of standard grammar rules, spelling variations exist everywhere.
