Delicious
Delicious (aka Katy Dierks) is Justin Robert Young's assistant, stat checker, and beer fetcher. She had never been seen or heard on either BBliveshow or NSFW for quite a long time, but had been mentioned by Justin several times. She finally made an appearance in the after show for Meat Drunk.1
The Justin/Delicious Fight Club Theory
Prior to her after show appearance and due to the mysterious nature of Delicious, some had theorized that she did not actually exist. Some thought Delicious was a imaginary person created by Justin's subconscious to fulfill his desires for friendship, companionship, and possibly sexual relations. There had been occasions when Justin had been seen talking to Delicious who was presumably just off camera, but no response could be heard.
Real Life
Katy has been a producer for shows such as Dancing with the Stars and The Marriage Ref.
