User blog:763492/About the title "Super Smash Bros."

Can you please tell me why's that title is called "Super Smash Bros."? Where's that title come from? And why's it has the word "Bros." on the title? That made me thought that the series is about brothers who fight each other, but no 'cause it always features characters from video games (like from Nintendo and third party companies). Don't you think some people in Japan always came up with weird titles when it comes to their projects? Honestly I'm not being racist about it, it's just that I'm just curious that's all.
