boom box bitch

Someone with a very average knowledge and and understanding of songs and musical terms but is always the one playing the music. This person is fine until you encounter his control over the music on multiple occasions. He would play the same songs and name the genre pretending to have a deep understanding.

Johno is such a boom box bitch. His plaist consists of 10 songs but he always insists on playing his music when we meet up. He also pretends to know his stuff about music but he actually doesn't know anything.
