An instrument many pick up for the sake of popularity. These people have no respect for the instrument as a musical device, but rather use it to look attractive to women or "cool" to men. Even the mere carrying of a guitar case or a small guitar pick will earn the bearer respect. This is the reason that many people walk around with their electric guitars even though they have no amp.
Poser guitarist: I spring-loaded my wallet so that every time I open it a guitar pick flies out. I don't even know how to play!
