The Guinea Pig Armor Charity Auction meme traces back to a 2013 eBay listing for a hand-made suit of scale mail and a tiny helmet. Created by user 'mightyspork' for his pet guinea pig, Lucky, the armor was auctioned off after Lucky's passing to benefit the Metropolitan Guinea Pig Rescue. The listing went viral due to its incredible craftsmanship and the hilarious juxtaposition of a small, soft creature dressed as a medieval warrior. It has since become a symbol of internet wholesomeness and creative fundraising. Today, the image is used to represent 'small but mighty' energy, over-preparedness for minor inconveniences, or simply to celebrate the absurdly adorable sight of a rodent ready for battle.
