[[caption-width-right:350:'''Men's General Etiquette''': ''To strike another man's groin is to be lower than a snake.'']]

->''"But the ball! His groin! It works on so many levels!"''
-->-- '''[[WesternAnimation/TheSimpsons Homer Simpson's]]''' critique of amateur film, "[[http://www.youtube.com/watch?v=mV1LWhNpTJU Man Getting Hit By Football]]".

It's not always played for comedy, but seeing someone get struck in the crotch is [[AmusingInjuries usually just plain funny]]. Whether the object doing the striking is an errant piece of sports equipment or a deliberately placed foot, the end result is going to be grown man doubled over and trembling with pain. Bonus points if he then hobbles away and [[InstantSoprano says something in a high-pitched voice]]. Not only will everyone find this hilarious, but tape it and play it back for the guy and [[ActuallyPrettyFunny even]] ''[[ActuallyPrettyFunny he]]'' [[ActuallyPrettyFunny will probably laugh]]. At least, once the swelling goes down. Sometimes a cause of AmusingInjuries, especially if the victim is [[AssholeVictim asking for it.]] In shows targeted at children it often times is a DangerousForbiddenTechnique (see ''ThreeNinjas'' and ''Film/MightyMorphinPowerRangersTheMovie''). In Japanese media, the blow is often accompanied by the sound of a bell.

Effectively, this is a human's version of AttackItsWeakPoint ForMassiveDamage.

A subversion of this is BallsOfSteel, where a character - for whatever reason - does not take damage from a Groin Attack.

Of course, this usually only applies to men, as women seem to be immune to the trope. Or that is, at least, how many depictions in popular cultures. In reality, females are no more vulnerable in their groin than anywhere else. A strike or squeeze to the vulva or clitoris will cause considerable pain and can incapacitate females due to the high amount of nerve endings in these structures. In extreme cases, the female victim may black out. The reason why females sometimes do not seem to suffer as much pain from a groin attack is because the vulva and clitoris, the parts of the female groin which cause pain when struck, are smaller than the target areas of the male groin, and are hence less likely to be hit. Nevertheless, a strike to a female's genitals can be just as damaging and debilitating as a blow to a male. Potential long-term health problems can arise for female victims of groin attacks including nerve damage to the clitoris, fracture of the pubic bone, hematoma, and vulvodynia. In many parts of the world, an attack on the female groin is considered to be sexual assault.

In contrast to most groin attacks, groin attacks that draw blood or involve some form of mutilation are very likely ''not'' to be played for comedy -- and owing to the PrimalFear of bad things happening to our nether regions, particularly nasty attacks of this nature can be downright ''[[NightmareFuel disturbing]]''. Apart from being a hallmark of the Lust variant of the SerialKiller, this form of attack is most often used as either a particularly vicious form of ColdBloodedTorture or as a way for {{Antihero}}es to punish rapists and other sexual criminals, though a particularly vicious CombatPragmatist may also use this tactic as just one more way to even the score or gain the upper hand in a fight. It may ''still'' come off as funny, though, if the guy is perceived as having brought it upon himself, such as [[PantsPositiveSafety having his gun go off in his pants]].

Also see StandardFemaleGrabArea (which is ''not'' the same area, instead the upper arm), EyeScream, {{Fingore}}, and TheToothHurts are other {{primal fear}} reactions. The DistaffCounterpart to this trope is BreastAttack. Often utilized by a CombatPragmatist, and commonly followed up by InstantSoprano and/or ShareTheMalePain.

'''WARNING, Reading these may cause extreme paranoia about injury to the pubic area and [[ShareTheMalePain wincing in sympathy pains]]. Yes, even if you're female. Also, this is ''never'' as funny in RealLife as it is on TV and can actually cause ''very'' nasty injuries, so for obvious reasons, DontTryThisAtHome.'''
