A shittercritter "shih ter krih ter" is a person who makes more money turning tricks in the bathroom than they do at their actual job, which is implied to be a stripper.
Yeah, we all call her a stripper, she says she's one, and her taxes say it; but she makes more money blowing guys in the bathroom at work than she does as an actual stripper. The bathroom has worse lighting, which means more money for her. Hence, she's a shittercritter.
Example 1
-This web page's images are cut up
-That's what you get when you use shitternet explorer.
Example 2
-Oh damn shitternet explorer opened by accident. Now it's going to ask me if I want to make it my default browser. Now it crashed.
Like 'The Happening' It's the sudden realization that the shit your holding in is worse than you thought. Often when you feel you don't need to go and an immediate urge to shit heavily comes from nowhere
