"I can't stand Roxie... She's a spoiled, inconsiderate and judgmental trust fund baby, when if you take away her looks and daddy's money, she's just a walking blowjob with an IQ lower than her shoe size."
"They would be delighted to tell you how suave they were at the drop of a hat/There was three of 'em/One of 'em thought she was a beauty queen/
The other one was a walking blowjob/And then there was a skinny girl"
-Frank Zappa, Jazz Discharge Party Hats (where I got the word from)

A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude.
