In 2015 after getting my first job and working for months, I managed enough funds to afford the fees for a school trip to China. We went to a sister school in a "small" city of 3 million people by the name of Binzhou, and stayed there for five days. It was a blast, and I made tonnes of friends and had a wonderful experience overall.
Decided to make Binzhou5 my username for a while using the city and the amount of days I stayed. Come when I went to Twitch however, nobody could pronounce the name correct (Bin Joe), saying Binzoo, Binzow, Binz house (reading the 5 as an s), and most commonly Binzo.
Eventually the streamer group I followed just shortened it and read my nickname to "Binz", with one of them later calling me "binzy", and the trend of slapping "boi" to end of it came shortly after. So I just decided to rebrand myself since everyone else had already done the same. Mind you, now some people in Discord are now reading my name as "Blinzy_Boi", all completely unrelated to each other, so that's odd.
