mcplain 

to complain without relent, to anyone who will listen, about anything, no matter its insignificance in the grand scale of the universe.

McPlainer: "My phone has ipod software on it.
And it sucks.
Theres a noticably gap between songs.
It's so aggravating.
Like when you listen to a live album or whatever,
and one song leads into the next...
it's so annoying...
its like a wholel second pause."
