** The best interesting part is during the offline meet where Hideki meets Ako in real life for the first time. When you look at the entire Alley Cats Guild online, you may assume that Ako's is the only female player. But the truth comes out when during the guild's first offline meet, it turns out that Hideki's the only male player in the guild. Turns out that his other two "male" guild-mates, Schwein and Apricot is actually his classmate Akane Segawa and the StudentCouncilPresident Kyou Goshouin. Guess this anime really fits the title.

* ''Anime/LoveLiveSunshine'': The post-series film, ''Over The Rainbow'', has the now second and third years of Aquors catching You Watanabe seemingly on a date with a dark-haired boy. After some time [[DatePeeping spying on them only to be caught by You]], the "boy", Tsuki, is not only revealed to be a girl [[RelativeError but also You's cousin]]. [[DownplayedTrope The other girls collapse to the floor in disbelief of their mistake]].

* ''Manga/IonoTheFanatics'': Well, [[GirlsLove Dropped a Bridget on Her]] really. However, inverted. Iono not only isn't uncomfortable with Tomo Senoo when she finds out the cute girl she was crushing on is a he, she's actually impressed... although this does disqualify him from [[IncompatibleOrientation becoming one of her concubines]].

This is both a [[TheReveal reveal]] trope as well as a character reaction trope, when what initially appears to be compatible gender attraction is later revealed to actually be ''incompatible'' gender attraction (''Example: Straight boy likes a girl, girl turns out to be a boy''). It is a sister trope to the related SweetOnPollyOliver, which refers to when what initially appears to be inexplicable ''incompatible'' gender attraction is later revealed to actually be ''compatible'' gender attraction (''Example: Straight boy likes a boy, boy turns out to be a girl''), although since the unsettling part is averted, this is usually a subversion (usually).

** A subversion: Hiroshi and Daisuke's discovery that the cute redheaded girl they were hot for is actually their male best friend does absolutely ''nothing'' to stifle their lust ("Why can't there be more girls like him?").

'''"Girl":''' Man, you must be up out your mind. *''[is actually Dr. Dre]''

* ''Webcomic/{{Oglaf}}''':

--->'''Charlie''': How was I supposed to know?"\\

* Taken to its most unpleasant extreme by ''[[https://en.wikipedia.org/wiki/Erythrinus_erythrinus Erythrinus erythrinus]]'', a predatory fish native to the Amazon. Juvenile members of this species mimic the appearance of the female members from the ''[[https://en.wikipedia.org/wiki/Laimosemion Laimosemion]]'' genus. When an amorous male of that genus comes seeking a prospective mate, he gets eaten.
* Shi Pei Pu (Chinese: 时佩璞; pinyin: Shí Pèipú; December 21, 1938 – June 30, 2009) was a Chinese opera singer from Beijing. He became a spy who obtained secrets from Bernard Boursicot, an employee in the French embassy, during a 20-year-long sexual affair in which he convinced Bernard that he was a woman. This is the basis of the play ''Theatre/MButterfly'', later adapted to a movie of the same name.
* There are several species of fish and at least one cuttlefish species among which smaller males mimic the color-patterns and body language of females. This is done to deflect large males' aggression as the small males sneakily insinuate their way into the large males' harems of females. Should the large male catch on while attempting to court such a poseur, this trope (and a nasty fight or pursuit) ensues.
* This is the reason why the term "trap" is considered a slur by the UsefulNotes/{{Transgender}} community, the implication of the term being that trans people (and especially trans women) are trying to "trick" people into sleeping with them, rather than just being who they are. Unfortunately, this can have serious consequences for trans people. In some jurisdictions, they can be prosecuted for [[BedTrick rape by fraud]]. Further, numerous trans women have been murdered after cis male partners learned of their status. A number of jurisdictions have (or had) the so-called "trans panic" defense, which permitted a defendant charged with murder in such a case to argue they flew into a rage on discovering this. If accepted, it could lead to acquittal or at least the charge being reduced (i.e. being manslaughter rather than murder).

* Near-future dystopian novel ''Literature/{{Victoria}}'' subjects the villainous Governor Hokem to this, with two attractive CampGay drag queens dressing up as party girls and getting him into a compromising position, resulting in blackmail and ultimately the end of his administration.

** Subverted in "The Fraud". After Principal Brown reveals that his diploma is fake, the other teachers proceed to reveal some secrets about them. Coach Russo proceeds to reveal: "And I am not a woman..." ({{Beat}}, everyone stares at her) "...who can say she's never lied on her résumé either."

*** This was later revealed to be [[IncrediblyLamePun jumping to conclusions]] in a [[http://sexylosers.com/g081.html guest comic that]] [[spoiler: both of her parents are crossdressers who are angry that their daughter isn't.]]
