Derived from "Shawshank" (i.e. "The Shawshank Redemption"), shankshawing is the process of slowly chipping away at a person until the ultimate goal is achieved.
Said "goal" is usually the love/affection of a person who is already in a relationship. First you become their friend, their shoulder to lean on when times get tough with their partner, the person they share their secrets with - then when they suddenly become single, what do you know? You are now their #1 option. BAM - shankshaw'd.
When Shrek and Thanos do the fusion dance, they create Shranos. Shranos is the strongest in the multiverse as he beat Ultra Instinct Shaggy without even trying that much. He can kill anyone just by thinking about it, and has the infinity gauntlet. He is the strongest being in fiction, and even obtained the unlimited N-word pass from Obama.
Red-Haired Shanks is a character from the popular and ongoing manga series and anime, One Piece. He plays a significant role in the life of the protagonist, Monkey D. Luffy, as he is what fuels Luffy's dream of becoming the Pirate King.
This man is the coolest character to ever grace the One Piece universe, and I need to see more of him.

Person #2: Are you kidding? Have you even READ/WATCHED One Piece? Red-Haired Shanks world domination, my dude.
Person #1: Dude, Aokiji can literally turn to ice. He's made of ice. He can make ice. He is the physical manifestation of "cool".
