My original gamer tag on Xbox was gameknight named after the Minecraft book series then when I moved to pc the name stuck around for a little bit on steam and eventually I wanted a silly placeholder name so it was SeñorFlipFlop.
Well the most temporary fixes are often the most permanent solutions and with the exception of discord all my usernames now are some variation of flip flop with my gta rockstar name being Flippy-Flopp and planet side being FL1P1E5FL0P
