for a long time i used 'caracal100' on everything because it was easy to remember and since a caracal is an animal almost nobody has heard i pretty much never had to worry about it being unique. but i kinda got tired of it, and to be honest i think having a username with numbers in it is just a little bit tacky.
so, one night i was bored and tried to start up this online game, and it was one of those kids games where rather than typing in your own username you're given a couple different lists of words to mix and match from and create your username from there. one list had the option rattlesnake. the other list had the option acrobatics. at the time i found this incredibly entertaining, and i started using it everywhere i could from there on out, and i'm still quite happy with it. problem is that "rattlesnakeacrobatics" is too long for a lot of places, so sometimes i have to shorten it to "rattlesnakeacrobat" and sometimes even that's too long and i'm just shit out of luck
