good, clean fun

Usually refers to activities that are rated for all audiences and does not involve any of the following: sex, drugs, alcohol or enjoyable activities that do not involve anything bad or immoral.

— Hantz: We have a party tonight at my aunt's house and me and my cousins will be playing a game of Monopoly.
— Frantz: Aaah good clean fun!
— For me, good clean fun is fun where there are no victims, and no damage done, physical or emotional.

Sometimes the phrase has sneering overtones as if such entertainment were boring.

Θησέα, νομίζω πως μπορείς να χρησιμοποιήσεις φράσεις όπως αγνή διασκέδαση, αθώα διασκέδαση, καθαρή διασκέδαση ή και συνδυασμούς των επιθέτων αυτών, π.χ. καθαρή, αγνή διασκέδαση ή απλή, αγνή διασκέδαση κλπ.

Επειδή o Δαεμάνος δεν λέει να επιστρέψει στο πόστο του, ας βάλω ένα κομμάτι της φίλης μου της Chan Marshall.
