A person who retains s*** on another person to use as leverage in an argument later down the line which has no relevance.
They have nothing else to attack a person with apart from that 'same old s***'.

What they do not understand is s*** will always be s*** no matter how long it's pickled
"Oh my god, why are you behaving like a shit pickler? It's not relevant anymore get over it Fred"

"Lucy, did he hear Julius starting an argument again with Poppy? I couldn't believe it, bringing up that old fake news, does he not realise that s*** will always be s*** no matter how old it is?"
"Yeah but come on Louise we all know he's the biggest shit pickler around here"

'Stop pickling s*** it's boring get something more relevant jeez'
