You misheard the phrase; it's "Sh-- rolls downhill." And it means that when something bad happens to a person in charge, it will happen to the people beneath him as well. For example, if your boss gets in trouble because he didn't do his job right, he's going to blame it on his assistant, who will then get yelled at. The assistant blames it on his team, who now have to work that Saturday. Eventually, the intern, who doesn't even know about the original problem, is getting yelled at and mistreated because people take things out on the people below them. Hope this helps. :)

For this reason, many lower enlisted Soldiers dreamed of the day they earned corporal, sergeant, and higher. http://greensickle.com/2007/04/ Reminds me of the rejoined we young airmen used to the over used military phrase “Shit rolls downhill” (which was meant to imply that we junior people had to simply deal with it). We began to respond “Yes, it does, sir; but it piles right back uphill.” http://blog.scottnolan.org/2006/09/ There is a saying in the army that ‘shit rolls downhill’, i.e the grunts get it for their officers’ cock-ups. Delivering a kicking to the high command for this incident is one thing, but stop bullying the poor bloody infantry, eh Alex? http://blogforbritain.blogspot.com/ A similar one is "Shit floats to the top." http://www.giga-usa.com/quotes/topics/proverbs_t282.htm
