My old XBL tag was "getliquorfaster", a reference to that ATHF episode "Bible fruit".
Then "Triforce_of_Wisdom" on WiiU and I use the handle Clefargle on Smash. Clefargle is just a fun way to say one of my favorite 'mons.
I use Euphemism for 3DS, Steam, and forums, and It's just me recognizing that my online personas are a nice way of presenting my personality through a lense. Similar to how euphemisms stand in for something worse. It's just an acknowledgement of that.
