to be organized, to be able accomplish a task
If you don't get your shit in one sock, you are never going to get that project done on time.

This term originated in the US Navy, and a "sock" is a term for seabag. A sailor who was not organized would not be able to put all of his belongings in one bag to be ready for quick deployment. Hence, the need to "get your shit in one sock".

After watching someone perform a task really well, you might say "Wow, that guy really has his shit in one sock."

While taking a dump, a person simply produces just one big long piece of shit that amazes the human eye. Although, this will be the only piece of shit you're able to get out during your entire bathroom session, the joy that comes with it is immeasurable. Common feelings include deep satisfaction, amazement, relief, and a well sense of being.
"I felt like my ass was gonna explode after all those tacos we ate man! But, instead I just had a one shit wonder! The thing had to be a good foot and a half long. So satisfying. So soothing"

Good grief, if you kids don't stop with this jackassery, I'm going to lose my shit!
