what's the most popular band in japan ? fall out boy
Are you making jokes about atomic bombs here?
izumi konno is my hero
I don't know who Izumi Konno is, but what you said about Fall-Out Boy sounded like it was a reference to the bombing of Japanese cities. To make light-hearted references to such a horrific event is not acceptable.
I feel like im living in the 90s
I am not sure what you mean here. Either way, just be careful with joking about sensitive topics. You may really make some people upset and emotional.
