* EarWorm: The [[http://www.youtube.com/watch?v=6JFhZcgou8s opening]] and [[http://www.youtube.com/watch?v=U8n-IvF8V0M closing]] credits have some nice tunes to them.
* EscapistCharacter: Averted for the male protagonist so far in a harem sense. Somewhat unusual given the genre.
** He is still an escapist character in a Zen way: he gives no damn about the world and calmly lives his existence unhindered by and unhindering nobody. [[HannibalLecture And he makes a strong point to others about his way of life.]]
** Though the escapism in that is still tampered by the realistic bouts of loneliness he faces due to being something of a social pariah by following his own philosophy (he even lampshades it once or twice). Bouts that come along as often as not. (Though perhaps it's more frequent in the anime.)
* FanPreferredCouple: Most of the artists from {{Pixiv}} are fond of [[LesYay [=Yui/Yukino=]]].
** At [[{{Imageboards}} 4chan]], [[StudentTeacherRomance [=Hachiman/Shizuka=]]] is likely the most popular pairing.
* FanNickname: At [[{{Imageboards}} 4chan]], Hachiman Hikigaya is better known as the 8man, Hikki, Batman, (The) Dark Knight or some combination.
** [[MemeticMutation Which tends to result in Hachiman getting photoshopped to look like Batman in most screen shots he's in.]]
* HoYay: Hachiman and Saika.
** Also Hachiman and Hayato, both in-universe(thanks to [[YaoiFangirl Hina's]] wild imagination) and in real life (apparently, Pixiv artists liked the idea a bit too much).
* JerkassWoobie: Both Hachiman and Yukino. Despite their abrasive personalities and cynical outlook on the world, they're both fundamentally lonely people who had to deal with isolation, rejections and bullying.
* LesYay: Yukino and Yui.
* SleeperHit: Overlooked at first due to mediocre animation and labelling as harem romance comedy. Highly appraised later by virtue of great characters and thorough exploration of their psychology and motivations.
