Inexcusable: (Adjective) Too bad to be justified or tolerated.

The details are still cloudy on why Jennifer Aniston and John Mayer split up, but one new theory emerging is that it has something to do with his twittering. Which, by the way, could have had a whole entirely different interpretive meaning 10 years ago.

Rocker JOHN MAYER said he was too busy to return calls while Jennifer was away promoting her new film. But Friends star Jen spotted he was updating his page of the networking site instead.

One pal said: “Jen was fuming. There he was, telling her he didn’t have time for her and yet his page was filled with updates! “Every few hours, sometimes minutes, he’d update with some stupid line. “She was like, ‘He has time for all this Twittering, but he can’t send me a text, an email, make a call?’ (Source)

I can totally see where she's coming from here. Back in the day, I used to have a boyfriend who was way into that "Warcraft" game and let me just tell you what a drag that can be on a relationship. Of course, the guy still returned my calls and everything, so, uh... Oh. She made the right decision, here. Maybe she should find herself one of those nice "Warcraft" boyfriends. True, there's the slight aroma of funk and mildew to deal with, but at least he's not going to be douching your personal life all over the internet.
