By using this word, you are letting others know that you are IN the happy state. Therefore, it’s more powerful in meaning than to say that you are simply “happy” because you are not only feeling the emotion, but being embraced and surrounded by it. The word “inhappy” can be modified as well, to fit the context at hand. “Inhappier” and “inhappiest” are two examples.
You’re at a concert and feel everyone’s exhilarating energy. Everyone is having the best time of their lives; everyone is inhappy.
