The type of person who goes to a retail park, buys a Starbucks, and then proceeds to walk into shops on the retail park and look at products with a glazed expression on their face. They have no real objective and they have no intention of buying anything. The soul purpose of a Buckslinger is to waste everyone's time, including their own.

A true Buckslinger will have one hand in their pocket while holstering the coffee cup in the other.

(Buckslinger is not just limited to Starbucks, and may be used to describe a person drinking from a cup with any coffee establishment on it)
Mike: Hey Paul, there is a Buckslinger down aisle three.

Paul: Ha, he looks like a cunt.

Mike: I hate Buckslingers, they are assholes.
