Funny folks - Boracay, Philippines

Alright, you can't say we didn't warn you.
Now it's not our problem anymore...

BOOM! There was a loud explosion somewhere in Boracay Main Road. I think the blast came from the top of the building in front of me. Some people scream, then they relax and someone even starts to giggle. I ask a lady who is standing beside me what that was about. She answers something that I can't quite understand. Run...done...bun...something of the sort. It doesn't make sense though, what does that mean? Hold on a second...no! It can't be. I ask again. She answers with calm, almost bored: "Someone shot a gun." What??? A GUN!!! And then she also starts laughing while she's talking about it with a storekeeper. 
This guys are fantastic. After all I should have already guessed that last year here.
