TIL:

Eutrapelia comes from the Greek for "wittiness" (Ancient Greek: εὐτραπελία, romanized: eutrapelia) and refers to pleasantness in conversation, with ease and a good sense of humor. It is one of Aristotle's virtues, being the "golden mean" between boorishness (ἀγροικία) and buffoonery (βωμολοχία).[1]
