"Six years ago, I wanna say, I was in my house, home alone, making a grilled cheese," Billie said. "I was almost done, you know, I was getting everything ready and I wanted some avocados, so I opened the fridge and was like, 'Where are the avocados?' And in my head I was like, that'd be funny if I made that my username. And then I didn't even do it! But then, a couple of days later, I was like, 'What was that thing I said? "Where are the avocados?"' That'd be funny as hell.' So I made it my username."
