no,it's not lazy to classify those who aren't being prim n' proper,those who are actively going against the submissive and breedable stereotype imposed on them,as gyaru.
Dude, gyaru tag was removed, you were wrong, can it already.
I won't,since Wikipedia itself shows that she is in fact filling the requirement.
Dude, One sentence from a giant article about a fashion style is not "the requirement." Gyaru is a fashion genre, and this is distinctly different from everything in that genre. There is a whole giant article there, with tons of pictures. You can just look and see this is super different.
Being stubborn doesn't make you suddenly right, it just makes you look like you aren't capable of learning.
