Billy Walsh was my first username, a character in Entourage. A guy I can relate to. He's really talented but the way he acts makes a lot of people not like him. He knows this and doesn't give a fuck and keeps being himself.
He's a film director. He drops out of the series for awhile and reappears directing porn. Vince (the main character and an actor) is trying to recruit him to return to films, and the following exchange takes place:
Vince: Hey come on, Billy, what do you say? You wanna make a movie?
Billy: I'm making movies, Vince. My way.
Eric: Your way? They're calling you Wally in there.
Billy: Wally Balls is my alias. It's catchy, ain't it? And they gave me a 25-picture deal after seeing me shoot only one scene. Billy Walsh is going to bring the 1970s-type class back to porn, and, the wide bush.
Wally Balls is my alias.
