The word krog originates from the grocery store "Kroger." A krog is someone who buys important goods there, not groceries. These goods could be anything, such as shoes, clothes, or dildos. It can be used to insult someone in just about any situation.
Wow look at that krog over there in the all black new balance shoes and sleeveless T.
