It is from gamertags, the original name you wanted it take it replace it with xX—Xx and your good, it is kinda of like the 1337 thing, something that distinguished there selves as a kid
Having “X’s” in your name originated from the hardcore music scene. It stood for “Straight Edge”, which refers to staying sober. Straight Edge Hardcore bands would play brutal music, but would not partake in drugs or alcohol after a show.
The term came from the black “X” that would be drawn on your hand with a marker at a rock concert if you were under 21. This was to let the bartender know not to serve you alcohol.
Please correct me if I’m wrong, but this is what I can remember.
I’ve been straight edge for 7 years this summer. anyways I am pretty sure it’s just a way to get the name you want. like if “name” was given you could do “xxnamexx” but if it was edge it’d just be one x on both sides usually.
