I think I caught something about that in some of the episodes of the Vresun. Such a niche obsession some people have!
It's strange isn't it? I think most of it comes from Kim (seriously, her DeviantART favourites are not for the faint of heart) considering that her sockpuppets (e.g Michelle/Ellen/Taylor/Ariana) all have same the obsession with lingerie/thigh-highs/anime girls.
