A shit list is a mental list of things or poeple that have annoyed you recently. usually completed in a mental top 10 of annoyances for the most recent times and used as a public display of annoyance without offending people directly.
If some-one winds you up.. they have entered your shit list. It's a more polite way of telling them where they can get off.
You could tell them that they have entered at number 1 on your shit list.
Or.. "That's gotta be top 3 on my shit list"
A term that was first used to found a (my) website of the same name (the address I cannot provide due to the advertising nature that would be, unless the site will allow me to). It means that something really winds you up. When something does wind you up, it's refered to as "gripping my shit".. as if the said situation has grabbed you right in the ass and is gripping whats inside. If your refering to some-one elses problems then it's described as "gripping YOUR shit"
The same site is also the public founder of the "Shit List": Basically, a personal list of items/people combined that griped my shit.
(Bitching about some-one) "That girl really grips my shit"
People that drive at 30 mph in a 50 really grip my shit.
(Talking to some-one) "What's Gripping Your Shit?"
"insert something that annoys you
.. It Grips My Shit"
