To be financially well to do, or generally fortunate.

term from the early 1900's where public places would have troughs to piss in and the piss would just run out, no runnning water or anything. The high price places would put ice in the trough so you piss would melt the ice and drain, producing less smell. therfore if you were rich you were "pissing on ice".
