Yeah I had to look it up [1]

> Eudaimonia (Greek: εὐδαιμονία [eu̯dai̯moníaː]; sometimes anglicized as eudaemonia or eudemonia, /juːdɪˈmoʊniə/) is a Greek word literally translating to the state or condition of 'good spirit', and which is commonly translated as 'happiness' or 'welfare'.

It's an interesting word. Using it can either attract or repel your intended MOTAS. I doubt there's a middle ground :-)

Uttering the word Eudaimonia at the company of hot girls will definitely get you laid.
