Though he does usually initiate the physical confrontation in relatively harmless areas like snowball or water balloon fights (and ends up getting plastered so severely it looks a lot less harmless), it's also quite common for him to just say something insulting to her and wind up with black eyes, bloody noses, or lying in a bruised heap on the ground.
Likewise, in For Better or for Worse, Elly slings coffee mugs and similar objects at her husband John from time to time, particularly in the strip's declining years as he fades Out of Focus by spending all his free time playing with his trains.An early MAD parody from The '50s deconstructed this by having an Art Shift on every other page where Jiggs is suddenly drawn realistically, and is covered in blood and scars, and has missing teeth due to his wife's beatings. In Bringing Up Father, the title character, Jiggs, would often have various kitchenware thrown at him by his wife.The woman would then hit him with any manner of objects. One running gag in Snoopy's stories was to have a man say a bad pun or something stupid.Linus' blanket whip is as far as it goes for the boys and that only gets used against people off-screen. Even Marcie is surprisingly eager to slug people in some strips. Lucy is the most obvious case but all of the girls have some level of violent streak.Charles Schulz also went on record in several interviews as saying that while a boy bullying a girl wouldn't be seen as funny, the gender reversal in a girl bullying a boy would. The other kids never really call Lucy out on this or try to stand up to her, and she rarely gets in trouble. Lucy is always throwing her weight around and slugging the other kids (not just Charlie Brown - probably her most frequent target is her own little brother Linus).The character Alice has a short, violent temper and often punches men with her "Fist of Death". And, of course, No Real Life Examples, Please!.
Also, due to the very nature of this trope, no Take That! edits, social natter or personal opinions please. Before adding an example, think about how the audience's reaction would be if the abuse was reversed. Note: This trope applies to abuse inflicted on males, not regular slapstick that can be inflicted on either gender. Regardless of the lack of physical strength, being hit by a weaker person still hurts more often than not, and there's a chance that some women may even the odds by using a weapon. The problem is that there are exceptions to both factors physically strong women and physically weak men do exist, and some of the former do take advantage of their strength to abuse the latter. Second, the majority of (reported) cases of physical abuse are male-on-female, making it more difficult to disassociate fictional male-on-female violence from real life. First, the average man is indeed physically stronger than the average woman, so male-on-female violence is generally more harmful. Sadly, there are factors that contribute to this belief being Truth in Television and violent women being punished less severely by the law than men in Real Life. Sisterhood Eliminates Creep can have elements of this. The female half of this trope is very often a Jerk Sue. A very similar anime/manga trope that does not always include abuse, but typically often will involve a woman violently beating a man and is played for comedy is Tsundere. Belligerent Sexual Tension often has elements of this trope. Related to All Abusers Are Male, All Women Are Doms, All Men Are Subs, Domestic Abuse, Double Standard: Rape, Female on Male, Men Are the Expendable Gender, and Stalking Is Funny If It Is Female After Male. An exception to either case is when one or more of the female characters involved in dealing the violence actively invoke this trope in an attempt to morally justify their own behavior, whether out loud or within the privacy of their mind. Obviously, it likewise doesn't apply in situations where female-on-male violence is treated as a serious subject. Nor does it apply in situations where universal humorous abuse is delivered to the Butt-Monkey or The Chew Toy by both men and women for equally flimsy reasons - that is just Comedic Sociopathy.
Note that this trope does not describe situations where violence is genuinely morally justified, such as Wonder Woman attacking Lex Luthor in defense of Metropolis.
