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.
