Imagine you are eating many diffrent root fruits. You take what you think is a potato but is greeted with a disgusting flavor and odd texture, that was a palsternacka. You got rolled and trolled. FeelsBadMan
Person 1: "OUAGH, WHAT THE FUCK IS THAT"
Person 2: " Oh, you don't like Palsternacka"
Person 1: NO WTF I THOUGHT IT WAS A POTATO"
*person 1 proceeds to kill themselvs*
A palster is a word that combines “pal” and “gangster” to describe someone who claims they are a gangster/dangerous person but they are innocent, soft and wouldn’t hurt a fly.
Bro said he was going to hurt me so I said “ yeah alright palster” and walked off.
