Eutrapelia comes from the Greek for 'wittiness' (εὐτραπελία), referring to pleasantness in conversation. It is one of Aristotle's virtues, the "golden mean" between boorishness (ἀγροικία) and buffoonery (βωμολοχία). Later on it came to mostly signify jokes that were obscene and coarse. The word appears only once in the New Testament, in Ephesians 5:4, where it is translated "coarse jesting" in the NIV.
