I think it is wonderful that adults like to play dress-up, be it for sexual purposes or just for fun. In fact, I even think it’s fair that we have a word specifically to describe the practice.
But the word “cosplay” was thought up by a monkey. A STUPID monkey. One with a brain injury and an incurable lisp. Also, the monkey is tied to the back of a door and people are throwing lawn darts at it. POISON TIP lawn darts.
Seriously, though. Just call it dress-up, okay? I know you think “dress-up” only applies to children dressing up as mommy and daddy, or as doctor and mommy, or as daddy and daddy (if they live in Massachusetts), but really is it any different when an adult does it? You’re still wearing an outfit so you may pretend to be someone or something else. Just because you may sometimes do this so that someone can pretend they’re also having sex with that frog, or that character from Final Fantasy, doesn’t change the basic premise.
It’s dress-up. You’re dressing up. But that’s okay. Nobody thinks you’re a loser any more than we already did.
