lolicore

Etymology
From. Last.fm claims it was coined by Loli Ripe in 2006 and their RYM artist profile says they were an anonymous 4chan poster - which doesn't seem unrealistic as the place of its origin, at least as far as the more western scene (which seems to be where the term "lolicore" came from).

Noun

 * 1)  A subgenre of breakcore that is characterised by heavily distorted and pitch-shifted samples, typically taken from anime, and often inspired by Japanese otaku culture.
