* HateDom: {{Tumblr}}, which is home to a massive fandom, is also home to a vigorous HateDom full of people who ravage the book and upcoming film for being pretentious, for taking cigarette use lightly, for spawning over-poetic fans, and, horror of horrors, for having been written by Creator/JohnGreen.
* {{Ho Yay}}: Isaac points out Augustus's "physical attractiveness" multiple times. Also, Augustus claims that his hot body caused Isaac's blindness. And on the dubiously canonical Q&A blog that John Green runs (see main page for link), Isaac is referred to as both "gay" and "a [future] ballerina." Both are said in jest, but still.
** Isaac accidentally grabs Augustus' thigh. The first thing Augustus says to him is, "I'm taken."
* JerkassWoobie: Van Houten. Yes, he's a drunk asshat, but you have to admit he is sort of a tragic character.
* MemeticMutation: This book (not to mention the author) is ''massive'' on {{Tumblr}}, mainly for being a massive TearJerker and a major source of feels. A common RunningGag is for newtime readers to document their first readthrough of the book and the progressive regression into a blubbering puddle of tears.
** "My x are x that I cannot fathom into x."
** "I the way you : slowly, then all at once."
* ViewerGenderConfusion: From [[http://imgur.com/gallery/tf78fHT/ the poster]] for the film alone, many people couldn't tell the gender of either person in the picture.
* UnfortunateImplications: Hazel and Isaac make out at the Anne Frank house. In front of the video of Otto Frank talking about his daughter. And people ''applaud them for it''. Because the Dutch fully appreciate horny teenagers desecrating a young girl's memorial!
** Sure, Augustus. Pretend to smoke a cigarette in front of the girl with ''lung cancer''. That's not a douche move at all, really.
* TheWoobie: Both of the leads, plus Isaac and Hazel's [[spoiler: and eventually Augustus's]] parents.
