->''"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=WUTVmuqviqE 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 a 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's often a DangerousForbiddenTechnique, or at least treated as one in-story (see ''Film/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 for massive damage. A subversion of this is BallsOfSteel, where a character -- for whatever reason -- [[NoSell does not take damage]] from a Groin Attack (or at least doesn't take ''extra'' damage).

Of course, this usually only applies to men, as female characters are rarely subjected to groin attacks of any kind. While female genitals are, if anything, even more vulnerable than their male counterparts, with lots of blood vessels and nerve endings close to the surface, they are also better protected than their male counterparts due to their configuration and orientation. Simply put they're harder to hit and lack the squish factor that comes from swinging in the wind. On the symbolic level a groin attack on a male--especially if it's delivered by a female--represents that male being brought low by the very source of his masculine pride. Since women don't typically evince that sort of pride in their genitals (female pride being associated more with [[BuxomIsBetter breasts]]) a groin attack on a woman just looks like cruelty. It's also an assault on the very source of all life, considered by many far too sacred for this sort of violation, and any sort of visual representation carries connotations related to rape. A groin attack on a man may appear funny; a deliberate groin attack on a woman usually looks like a sex crime.

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 [[LaserGuidedKarma 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]]. See CripplingCastration for examples of groin attacks that lead to the unfortunate victim losing his organs/the ability to procreate.

Along with TaserTagWeakness, the GroinAttack also seems to be very effective against {{Superhero}}es and {{Supervillain}}s, although [[BallsOfSteel some of them are immune]].

Compare FreudianThreat. 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 unless you are in a real self-defense scenario, DontTryThisAtHome.'''
