look up any word, like bukkake:
The pure bliss and fulfillment that comes with success, or a person who experiences this bliss. Comes from the fact that, always swimming and killing, otters can't help but be happy.
After the presentation, James emanated "Happy Otter." I knew things had gone well.

When Nate's jump shot starts falling, he is happy otter without fail.
