Get the Steam Trainmug. a myspace group (usually called something with 'vanity', 'deadly', 'perfection', or 'morbid' in it) that has a bunch of scene kids who have never met in it. they are a train because twice a day everyone has to post a bulletin with pretty people's pictures in it. bear in mind you must have it least 5000 friends and must be GORGEOUS to make it.
