Using LMAO in formal settings, such as professional emails or academic papers, would be highly inappropriate and could be perceived as unprofessional or even offensive. The intensity of the laughter it implies is also a factor; it suggests a level of amusement that goes beyond a simple chuckle or smile, indicating that something is exceptionally funny.
