I don't know if it's a woman's constant need to turn shit into an argument, but when it boils down to the basic "who has it worst" question, they always pull out the periods, pregnancy and appearance bullshit. Guy problems can vastly overshadow this, and I am compelled to list such!
1) When you break up with us, it takes you about 5 minutes to have a new guy as you women have no feelings of loyalty to anyone but yourselves. It may take a man years to find another, with the possibility of history repeating itself.
2) You can have all the sex you want, you don't have to worry about getting anyone pregnant.
3) Peacocking. Wikipedia that shit.
4) Girls get to talk with other girls about how they like. A guy telling other guys turns into him having to prove his worth.
5) Women always complain about how guys are assholes. Chivalry is dead, and women killed it with that feminism and sexism crap.
6) Ugly girls can buy a fuckton of sex toys with no qualms at all - a dude buying a fleshlight makes Fox News at 10.
7) Girls are expected to be all emotional and shit. A guy tries to show his emotions and he's gay.
8) Testicular trauma has been proven to be exponentially more painful that childbirth.
9) Girls can accessorize all they want. Aside from hair gel, a guy showing preference for his brands is gay.
10) Nobody fucking asked you to get pregnant, shut up.
11) If they don't fit into a certain clique, girls can always pull that "Miss Independent" shtick. What can we say that would deter you from the impression that we're loners?
12) Some girls can look sexier in sweats and their hair in a bun than with a tight skirt and make-up. We either look like Hollister models or bums.
I can't think of any more shit off the top of my head, but I've barely scratched the surface, trust me.
Converse amongst yourselves!
