I suppose I don't exactly understand the concept of a pajama party. Although I've clearly never been invited to one, since that's not the type of thing that males do, from what I've heard and seen on reruns of old television shows, way back in the day when writers actually attempted, albeit vainly, to make the programs they produced actually contain some small iota of value, a pajama party (a.k.a. slumber party, a.k.a. sleepover) consists mostly of teenage girls getting together to do each other's make up, talk about boys, watch movies, call the boys they talked about and then hang up quickly after they answer, or illegally break into the hostess' parent's liquor cabinet and learning a valuable lesson about the dangers of alcohol.
Is that really...all it is? I suppose I can fathom the appeal of doing so, if that's the kind of thing you enjoy. I just don't understand why it has to be overnight and in your pajamas? Can't any of those activities be equally appealing to do during the day in your normal clothes?
I've been trying to think of the male equivalent to the pajama party as well but I haven't come up with anything except to crash a girl's pajama party. I'm not sure girls realize this, or maybe they do which is a secret ulterior motive to holding a pajama party, but most adolescent males have the idea that when girls get together for things like this, they're dressed in all of those fancy girl pajamas, or maybe just their underwear, crawling on each other having pillow fights and practicing their kissing skills on each other. Which, of course, you probably aren't.
Thus, I can only gather that the real purpose of a pajama party is secretly, and maybe even unbeknownst to both sexes, just another step in the weird mating rituals of the human race. The proclamation "NO BOYS ALLOWED!" is, of course, only going to guarantee that boys will attempt to somehow be apart of it. While it's highly likely boys would have attempted to crash the sleep over regardless, adding that last little bit seems to me to be a subconscious display of desperation for a little bit of excitement and soft core male attention so the girls involved can both have fun with their friends and feel at least a little bit hormonally satisfied all at the same time.
I'm not entirely sure what the purpose of this post is other than that.
