What happens when 80% of the fangirl population sees something cute like a character match-up and/or is reading a yaoi. Requires lots of flailing around, making kitty faces and screaming "OMIGOD!" or "SO KAWAII!"
Did you see Samantha back there? I think she was diagnosed with Retarded Fangirl Syndrome after she saw that Maka X Soul match-up.
