Noun- The very subtle relief one gets while doing something that they overwhelmingly feel guilty for.
Etymology- That low, dirty feeling you get when you log into MySpace yet again.
So, I was on Facebook because I am a socially inept student, and my curiosity pervaded my veins, and I decided to log into MySpace, to see if anybody paid any attention to me. They didn't. But the Myspacesque pleasure attained made up for it slightly.
