My friends and I have an event. Someone sucks and you want to give them a get fucked/you're a loser. Rocky area...you turn away from them. And kick the rocks at them like a cat in a litter. It's called Kitty littering someone.
He wouldn't shut up so I ended up Kitty Littering him before walking away.
To hit someone with a bag of scooped kitty litter.
I just kitty-litter-bagged my hand when I was throwing the kitty litter into the garbage.
