Either a 27 year old woman with a boob job, or a gay man with a great job. Both claim to have many friends that are also foodies. They see Rachael Ray have foodgasms and expect the same from Burger King.
They spend too much money trying to emulate food celebrities they see on Bravo, and do ridiculous activities like going out in a party of 10 to a Kobe beef tasting.
Essentially, if you call yourself a "foodie", you aren't one; or you aren't what you think it means. A firefighter would not walk up to a burning building, criticize the flames, and proclaim that he and his coworkers are firefighters.
"This restaurant sucked, me and all my friends are foodies, and my steak wasn't hot enough, and there were some sea salt crystals on my bread."
