floaty head
The floaty feeling you get in your head when you have just eaten Mexican food. It feels like the best thing that has ever naturally happened to your head. Your brain becomes gently surrounded and cushioned by fluffy clouds. You might be having dinner with friends and notice your head is floating away, metaphorically speaking. Just relax, it was meant to happen.
Hey, I'm in the mood for Mexican food tonight because it's delicious and I know at the same time I will most likely experience floaty head.
