The term "store-bought" is an insult to those who call themselves a "hero-fan".
It is refers to someone who buys a hero costume in a store instead of making it themselves.
You often hear this term in hero-related conventions or in hero-related social media groups such as Nitpik.
Many a hero-fan brawl was started when someone's outfit is referred to as "store-bought".
"Store-bought" can also refer to a hero whose attire is a generic template, such as the blue-and-yellow bodysuit that is the default outfit for all heroes. Heroes who appear wearing this are called "Store-bought" as they don't even take the time to come up with an original outfit.
