Ash
I was a huge fan of pokemon as a kid. I loved the show, and my parents despised having to go to the theater with me.
Well, when I was smaller, I had a lisp. A pretty bad lisp. So when I said “Ash Ketchum,” it sounded like I was saying.. well, you know.
(another word for donkey, a bad word for butt)
It makes me laugh. So I used it as my avatar.
Not the most interesting story :)
