Kind of like fishing for compliments, this is someone who "Fishes" in the same way but for criticism. People do this to build sympathy from others and depict themselves as a victim. Often times, it's obviously fake. btw, the "Boots" and the "tires" can be used interchangeably.
"Omg Cathy keeps fish'n for boots n' tires. I can't believe people are falling for this."
