Wondering exactly what a windorphin is? According to Ebay’s latest online ad campaign “windorphs are addictive substances in the body that are triggered during victorious moments (ie. winning the spelling bee, lottery etc). After a big win windorphins deliver a general sensation of unabashed joy in the brain, leading to heightened energy, exuberance and outright slam dunk high-five behavior.”

Randomly enough, Ebay has tracked the shopping behavior of its users and posted a list of the brands deemed as “top windorphin activators” in the jeans category:
