Gagalistic
When something is so good, it feels like your brain is exploding and your mouth is full of glitter and bad decisions.
I saw a meme so funny, I laughed so hard I cried and my dog ate my homework.
That pizza was so good, I tried to eat it with a fork and a spoon and both broke.
My teacher said 'good job' and I screamed 'this is gagalistic' and got sent to the principal's office.
