Just a show

• 1. I don't know if this is a thing outside of Bulgaria, but it's a phrase meaning that you will stay in a bar until the staff tells you they are about to close, or you see them, for example, starting to clean
• 2. This line refers to a controversy from the summer, when a minister personally closed down bars in the biggest Bulgarian resort, Sunny Beach, already at midnight because of noise complaints
• 3. It's a wordplay in Bulgarian - "чукам се" could mean both people clinking their glasses together or having sex
• 4. In Bulgarian you are not obliged to specify the vessel a liquid is in - you can say "a coffee", "a water" and people would know the vessel from the context; here, it's left pretty ambiguous whether it's a glass or a bottle, so I also didn't specify it in the translation
• 5. Another concept which doesn't really exist in English; in Bulgarian, we literally say "I greet/salute/congratulate you with this song" and nothing more than that, which means that song is probably the other person's favorite song or they have a story with it or something along those lines; in a club context (and probably also in the song, considering the next line), you may also go to the DJ, say the name and they will say "for [insert name here]"; it's not really much of a dedication, but that is probably the closest in English
• 6. A bit of a humorous phrase, that is often used when person A is mad at person B, so they call them over, because they "need" them
