-->-- ''Series/WhoseLineIsItAnyway''

Let's say you've got someone with an AmbiguousGender on your hands. Either the DudeLooksLikeALady or the LadyLooksLikeADude. The mystery is driving you [[JustForPun nuts]], so what's the fastest way to figure it out?

Inspect the merchandise. ''By force.''

When it's done to one's own self after a GenderBender, it's ManIFeelLikeAWoman.

DoNotTryThisAtHome. It's one of the class of acts that are known as 'sexual assault' in the real world.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* ''YuYuHakusho'': Yusuke figures that there's something a little off about a certain FemmeFatale opponent, so he pulls a reach-around mid-fight and finds that she's biologically male.
** In the EditedForSyndication American dub, all the references to the [[DudeLooksLikeALady female fighter actually being a man]] were changed to the fighter being a ManipulativeBitch who fakes her injuries so she can make her male fighters feel guilty about beating up a woman -- and uses that moment of weakness to strike back.
* ''DragonBall'': The young Goku had difficulty with the concept of males and females, so when meeting someone, he goes up and slaps his hand in the person's crotchular area, then triumphantly exclaims, "You're a boy/girl!" Notably, this causes Chi-Chi to ''push him off the Flying Nimbus in fright.''
** He first discovered this connection in the first place by pulling the panties off of a sleeping Bulma and realising that she's missing some parts that he has. Bulma did ''not'' take it well when she found out.
** Krillin managed to escape this treatment by telling Goku beforehand that he's male.
* In season 2, episode 6 of ''Manga/GirlsBravo'' Fukuyama doesn't realize a cross-dressing Yukinari is actually a guy until after he grabs his crotch.
** Of course, in this case, he hadn't doubted that Yukinari was female yet.
* This happens to Takatsuki, a male-transitioning-from-female {{Transsexual}}, in ''WanderingSon'' once. It's {{Squick}}y being that he was around ''eleven'' then and the person who did it was an adult male (who later became his friend) who thought he was having an affair with his girlfriend. Takatsuki just puts on a brave front afterwards and holds in his tears.
* In ''FushigiYuugi'', Miaka rubs Hotohori's chest after finding out that Hotohori [[DudeLooksLikeALady was not a girl]]. She does it again with another character...just to be sure.
** Even funnier, the second time she does this is to a woman who doesn't look even remotely masculine. Despite the fact that they had literally just met only seconds before, Miaka gropes her breasts purely on the basis that Hotohori and Nuriko have already fooled her before, and she "figures I have to check these days."
* ''SteinsGate'': Okabe does this to Ruka some time after [[spoiler: she changes her [[GenderBender gender]] with a D Mail]]
* ''Manga/{{Gintama}}'': Gintoki pulls this off in the most {{Badass}} way possible in chapter 375.
* In ''Manga/OtomeNoIroha'', Ryou checks Iroha's gender ([[GenderBender now male]]) this way the moment they first meet.
* Done with Tetsuo, a transman, in ''Manga/{{Yuureitou}}''. Marube, a criminal prosecutor, overheard him talking to Taichi about his body earlier and questions him. Tetsuo isn't aware that Marube knows he is [[spoiler:Rika, a woman who killed her mom and supposedly died two years ago]], and tells him he meant he has a [[TeenyWeenie micropenis]]. Marube does the crotch grab to check and (obviously) doesn't feel anything. Tetsuo keeps to his statement and says he's just small.

[[folder:Film]]
* ''Film/CrocodileDundee'' has Mick flirting with a veiled woman. The cab driver he's been getting drunk with informs him that she's a biologically male. Mick walks right up and checks the crotch for the frank and beans. She, offended, stalks off. Later in the movie, Mick sees another rather ...handsome... woman and does it again. To his chagrin (and her delight), she's the got the full female package.
** Bonus points for the first one being performed in the middle of a crowded bar, without so much as a "Hey, mind if I check something?" He literally just reaches across a good foot of separation space and does it, much to the hysterics of all the onlookers! "[[CaptainObvious She's a bloke!]]" indeed.
*** Extra bonus points for the character being portrayed by a biologically female actress.
* Occurs in two very different contexts in ''Film/TheKingAndTheClown''. One of the Seoul jesters gets groped by audience members for this reason whenever playing a eunuch or a woman. In a much more serious moment [[HotConsort Nok-su]] forcefully strips [[{{Bishonen}} Gong-gil]] in a fit of [[ClingyJealousGirl jealousy]], claiming she wants to find out whether he's really a man or not.
* A variant occurs in ''Film/{{Transamerica}}'' when pre-op transsexual Bree visits her mother. Her mother performs the grab in order to check that she's still physically male.
* Begbie in the film ''Film/{{Trainspotting}}'' chats up a woman at a club and takes her to his car to get to know her better. After 'inspecting the goods' he finds out she is a transvestite and kicks her out of his ride.
* In ''Film/EscapeFromLA'', Snake meets a female gang boss named Hershey who has an unusually deep voice. He immediately recognizes the voice as an old buddy of his. He proceeds to perform this trope. It's not clear what he finds. It's clear the buddy had a sex change. It's not clear how complete it was.
** When Snake pulls a small pistol out from between her legs, that he was searching her for the weapon.
-->'''Snake:''' "Still keeping a [[DoubleEntendre loaded gun]] between your legs, huh Carjack?"

[[folder:Folklore]]
* The ''sedes stercoraria'' are seats upon which a new pope is enthroned, which have a hole in seat. A popular rumor says that these are so that the college of cardinals can test if the new pope is in fact male, or if he has mangled genitals. Most historians now believe that they were just chairs that the Papacy used because they belonged to the Imperial family.
** The sex-check story is generally associated with the [[SweetPollyOliver "Pope Joan"]] [[http://en.wikipedia.org/wiki/Pope_Joan historical legend]] -- according to that story, the cardinals took this precaution against a recurrence.

[[folder:Literature]]
* In the Aidan Chambers book ''Postcards from No-Man's Land'' the main character meets someone he assumes is a girl, and they have coffee. At the end of the meeting, the "girl" figures out that the main character thinks this, and grabs the main character's hand and puts it on his crotch before leaving.
[[/folder]]

[[folder:Live Action TV]]
* In one episode of ''LawAndOrderSVU'', the investigators discover that the boyfriend of the perp [[UnsettlingGenderReveal didn't know she was a preop transsexual]] when they tell him why she killed his best friend. He rushes in, grabs her crotch to see if it's true, and then overdoses on pills.
* As quoted above, [[http://www.youtube.com/watch?v=N2oqBO1K4pU this]] Party Quirks game of ''Series/WhoseLineIsItAnyway'' has a humorous version.
* Less invasive variant in ''{{Bones}}'' where the sex of an androgynous Japanese detective is determined by a firm hug.
* Pat from ''SaturdayNightLive'' narrowly averted this a few times.
* In ''Series/{{Casanova}}'', Casanova falls in love with Bellino, a male opera singer. He suspects that he's a girl and confronts him. He feels his chest and concludes that he's a girl. Bellino says it is a singer's condition. Casanova grabs his crotch and then runs off, he is a boy. Then later he comes back and tells him it doesn't matter and he still loves him. Turns out to be a false penis and [[SweetOnPollyOliver a woman in disguise]].
* Chiana uses the milder "rip open jacket to reveal breasts" version to a woman disguised as a man in an episode of ''Series/{{Farscape}}''.
* In an episode of ''Series/LostGirl'', Bo outs an incubus cross-dressing as an Amazon by grabbing the family jewels. The Amazons quickly set on tearing him to pieces.

[[folder:Theatre]]
* In some productions of ''{{Cabaret}}'', this is how the MC tells Victor and Bobby apart. (Maybe Bobby is really a girl?)
[[/folder]]

[[folder:Video Games]]
* ''Franchise/MetalGear'':
** In ''VideoGame/MetalGearSolid2SonsOfLiberty'', President James Johnson greets {{Bishounen}} hero Raiden this way to check his gender. The moment is parodied in Webcomic/{{Hiimdaisy}}'s "Let's Destroy Metal Gear Again" in a series of panels that provides the page image above.
-->'''Raiden:''' YOU ARE THE WORST PRESIDENT EVER.
** The moment was [[CallForward referenced]] in the prequel ''VideoGame/MetalGearSolid3SnakeEater'', although the moment itself is an aversion: The game's BigBad, Volgin grabs the crotch of [[PlayerCharacter Naked Snake]] (disguised as Volgin's subordinate Ivan, a clear parody of Raiden from the above example). However, the crotch grab is not to check Ivan/Snake's gender, but their identity. [[spoiler:Strange thing is, he is able to identify Snake as an impostor just from this moment, implying that this is a regular thing between him and Ivan. Considering he is also implied to have raped EVA, this isn't too out-of-character.]]
* ''[[VideoGame/Disgaea4APromiseUnforgotten Disgaea 4]]'': Jokingly invoked and [[IWasJustJoking then]] defied by the same person, when you talk with the thief in the Campaign Board.
-->'''Thief:''' "[[AmbiguousGender My gender?]] Why don't you have a little poke and find out for yourself? ...Wah! I wasn't being serious! I'm [[AmbiguousGender tot]][[DefiedTrope ally]] a girl, I swear!"
* [[spoiler: Chihiro Fujisaki]] from ''{{VisualNovel/Danganronpa}}'' invokes this by moving Naegi's hand onto his crotch after he confesses his true gender to him.

[[folder:Webcomics]]
* An accidental example occurs in ''{{Drowtales}}'' when [[SweetPollyOliver Ariel]] is in a fighting class and another student goes for the groin, [[http://www.drowtales.com/mainarchive.php?order=chapters&id=208&overview=1&chibi=1&cover=1&extra=1&page=1&check=1 only to discover that what he expects to be there isn't]]. This alerts him that something is up and later outs her as a girl.
* In one of Kate's pre-''Webcomic/AwkwardZombie'' [[http://hail-nekoyasha.deviantart.com/gallery/#/de5sim strips]], [[VideoGame/TheLegendOfZeldaOcarinaOfTime Link]] decides to try this on Sheik ForScience. Unfortunately, since he actually used a GroinAttack, it didn't prove anything.
* In ''Webcomic/TheOrderOfTheStick'', Belkar attempts this on Vaarsuvius, by taking advantage of the wizard being turned into a lizard, to find out if the elf is male or female. He is foiled by his lack of knowledge in lizard anatomy.
* ''Webcomic/{{Karin-dou 4koma}}'': Aiina only knows Elza (a {{Hermaphrodite}}) as a standard for magicians, so when she first sits down with Seren, she checks if Seren is similarly equipped.
[[/folder]]

[[folder:Western Animation]]
* In a subversion, the leader of an all-girls gang does this to Steve (clearly male, if a bit over-sensitive) on ''WesternAnimation/AmericanDad''. She promptly concludes that he's more girl than boy, and offers to let him join. [[NoHoldsBarredBeatDown Initiation follows]].
