Welcome to McDonald's, Can I offer you a J-Mac?

So I just found out that Jesse McCartney now calls himself J-Mac? When did that happen, and what the freak is he going through? J-Mac? Really?

"Oh hey, what are you listening to?"
"Oh just some J-Mac."
"...wth."

And that's what would go down.
Was he at McDonald's when he decided it? Maybe eating a Big Mac?
First bite: "Oh-em-eff-gee, dad! I want my stage name to be J-Mac!!" *Squeals like a 3 year old*
Dad: "wtfbbq."

Because that's what it sounds like. Like a freakin' McDonald's "throw back" food. "Oh, I'll take a J-Mac, a large fry, and a diet soda."

No. No, Jesse. No.
I didn't like you much before either, but now...just no.
