Hi, everybody! Thank you for all your answers. I have a question about the word . I hope it is not a bad word since it is not in this wonderful dictionary. Well, I see it in many comments on YouTube, so what does it mean? Is it a slang? How is it acceptable in writings (such as a book)? In case you need some examples, I show some YouTube results for this word, such as: (1) Κουράγιο ρε Παντέλη! (2) Δε σου φτάνει ρε; (3) ΑΝΝΑ ΒΙΣΣΗ- ΡΕ! (4) Σταυρος Κωνσταντινου - Α ρε νυχτα (5) Tus - χόρτο ρε βλάκα (6) ΤΡΑΒΑ ΡΕ ΜΑΓΚΑ ΚΑΙ ΑΛΑΝΗ - Σοφία Παπάζογλου. That's all. Thank you so much for supporting me whenever I ask for help here!
