A sad and rather pathetic person who goes to as many music festivals and concerts as their parents can afford. Not for enjoyment, or love of the music but so that they can show off their tatty collection of wristbands along with their tan at the end of the summer.
Penelope: "The red one's from Reading and the green one's from Glastonbury. The purple one's from this darling little place in Italy that I went to whilst Daddy was on a business trip there"
John: "Which band did you like best then?"
Penelope: "Band? Huh?"
John: "Gah - you are such a Wristband Collector"
