Not kill themselves Or song lyrics as the caption. Any badmouthing a tumblr girl's fandom or obsession will result in an army of anon asks in your inbox telling you to die because you don't appreciate art. They are all generic and are annoying. They will then beg their audience with some quote seeming all nice, to attract a rather sensitive appeal to their audience as well as being a looker. Those damn tumblr girls won't give it a rest!
See, that’s what the app is perfect for.
A 'Tumblr girl' is a person who wants to build their ego by taking pictures of themselves in which in modern day "mainstream" fashion.
Posting it onto whatever social website they want, and sharing it plenty of times. She keeps on going until she has K Followers or something and then gives her account away. A Tumblr girl holding up a piece of paper in their mouth saying "BeYouTiful". She shops at Brandy Melville and Urban Outfitters and has christmas lights and band poster in her bedroom!
