<human>: Can you provide a brief overview of the text?

Like most Fuck ups this didn't happen today but a year ago. [Another TIFU i read today reminded me of my fuck up!] Let me paint you a picture of the situation. I was living in Osaka, Japan as an exchange student. So me and some other European friends were at some club, in Osaka, just having a good time. 

Japanese girls are very shy but also interested in European guys. So I'm hitting it off with a beautiful girl and I'm feeling confident I'm  taking her home (or you know, a love hotel for a couple of hours). I just assumed so was from Osaka but then she told me she was from Nagasaki. And there is where my fuck up was born. In my drunk state of mind i thought i would be funny to say ''Nagasaki? i heard it was the bomb!''

I'm laughing, my friends literally laying on the ground laughing, but she wasn't laughing. I never saw a cute girl go from happy to batshit crazy in just 0,5 seconds. She was furious and stormed out of the club, with her friends.  Needless to say I did not get lucky that night. My friends got angry because they didn't get lucky, but we still laugh about the joke. In the end it was worth it.
<bot>: I said ''Nagasaki? i heard it was the bomb!'' to a hot Japanese girl in the club. She got pissed, i did not get lucky.
