eBay mong
A person who thinks everything on eBay is worth $100, even if it's a rusty spoon from the 1980s. They'll buy it, then yell at you for not shipping it to Mars.
I paid $200 for a spoon. It was rusty. I yelled at the seller for 15 minutes.
I thought a 20-year-old sock was a luxury item. I was wrong.
I bought a 'rare vinyl' for $150 and it was just a beat-up record from the trash.
