I love meme cosplays. XD I have a Hipster Ariel cosplay that I went out of my way to put together. Helvetica is really fun to wear. Especially since I get to make the weirdest expressions.
I've seen a Nyan cat before, and that made me super happy. Meme cosplays are always hilarious. I especially love Slenderman ones. I laugh everytime the cosplayer always tries to scare people when they're Slenderman. xD
