When you are having a great time and something makes you too excited so you can’t control your emotions.

1.) The new minecraft update is making me so inharious.
2.) I’m in the process of being inharious from that food my mama made me.

3.) “Dude, he looks like he’s having a good time, he must be inharious right now.”
“Yea, I wish I felt like that.”
