Do I want to know wtf that is?
@ModernPost
Since no one replied to it, basically pelvic area. It's an old anime subtitle meme from Yumekui Merry beach episode.

For context, he's actually commenting about why she was wearing a school swimsuit at the beach, and the subbers just took some liberties with it and... yeah. The manga is a bit more clear about it.
