Similar to the idea behind "don't cry over spilled milk", this phrase is widely useful. In a situation where something sucks for person A, person B might have the feeling like, well what are you gonna do, you cant do anything, so get over it, as in shit in a bag, man, there's nothing you can do about it. Thus, person B would say, shit in bags.

Person A: "My bikejustgot stolen!"
Person B: "shit in bags, man, nothing you can do about it."
When the sacred rule of not taking the urinal next to someone is broken and turned up to 11. Lots of people, usually with dicks, piss fuck and innocent urinal user. This will only happen when nobody else is around, so please always take a friend with you to a public toilet… not in a gay way, unless you’re into that but thats not the point. Bring a friend, be quick, and happy safe piddling guys.
Person 1: “Hey man did you here about the public toilet incedent?”
Person 2: “Wait it was true?!”
Person 1: “Ya, its the worst urinal gang bang this town has ever scene.”
