Lolita, or child porn pictures of the softcore variety, as opposed to the hardcore netropic. It is an underground japanese term and Urban Dictionary doesn't support the reference kana at this time. The term originates from the earliest days of the internet in Japan, pre World Wide Web. It was not illegal in Japan, in those days to possess images and Japanese culture allowed magazines with Ro and Roritapictures to be sold on newsstands. magroripictures were traded in the newsgroups called youth-and-beauty because they were softcore and had less trading value. This is all part of a movement called rorikon, or "lolita consciousness" based on the forbidden love affair in Nabokov's famous novel.
Yasuhiro has many netropic because he is yakuza and some magropic, would like to trade.
