Uforia
The sensible way to spell Euphoria, so in the historic times when rich scholars wished to keep the peasants ignorant, the scholars spent their days concocting new ways to make the written language more complicated. Hence instead of "U" we have "EU" and instead of "f" we have "ph". Uforia the powerful overwhelming feeling when a person is is high. Often associated with pleasure, excitement, smiling, laughing, dancing and a high level of confidence.
On completing the marathon I experienced a state of uforia. Even though I had worked hard all year upon receiving my exam results I was in a state of uforia all day, joking, smiling, laughing and full of confidence.
