You know, I certainly don't expect everyone to know who every cosplayer at Comic-Con is dressed up as, but considering that both Jean Grey and Psylocke are relatively common and considerably more mainstream than, say, Ms. Monster or Danger Girl, it wouldn't take much research to find out who this character is, even if you had no clue. I don't know; it just seems to me that if you're trying to blend in and be part of a crowd (of any sort) you should at least make it less than obvious that you're really just a poser.
But maybe it doesn't matter in this case? Despite the popularity of the refrain, I doubt many guys are on the Playboy web site for the articles.
