To be in a bad situation which is either slowly or rapidly getting worse with no evident way out. Should you be armed with a paddle, you still, typically, have a slow long recovery

To be in an undesirable place, or to be in trouble. A contraction of "Up shit creek without a paddle." It can be made to define even more extreme circumstances by adding the suffix "with the repo men on the shore waiting for the boat"
"I was up Shit Creek without a paddle, and the repo men were waiting on the shore for the boat."
