Seriously guys?
Soooo many Japanese accessories will literally just have english swear words on them for no reason other than to look cool. I kind of doubt this hat is Ayu's take-that at her haters or anything - she probably knows what it means and just thought it was funny. This is coming from the girl who typed "WHERE U @ BITCH????" in a PV and who wore a hat saying "CHIP CHIP pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~pretty pony~S" or something absurd like that a while back
She's just having fun, don't look into it too much
EDIT: uh... censor filter still on, I guess?
I meant "CHIP CHIP MOTHERF*****" but i'm gonna leave that mess of pretty ponies because it looks fun :3
