A genre of Japanese (hence the "J") music that incorporates characteristics of both J-rock and J-pop. Similar to "Pop Rock" in that the music emphasizes lyrics, has a catchy melody, but has guitar-driven music. It often, but not always, covers less "bubble gum" topics in favor of more sophisticated, socially influenced topics.

While I was listening to Green Day, I saw this guy eat a handful of Pop Rocks followed instantly by a swig of Coca-Cola, then his head exploded like a watermelon.

when you take pop rocks and shove them in a persons anus. You then add pepsi or other carbonated beverages to cause a reaction. Right after putting the pop in the anus you give it in the anus causing to mix the chemicals. the result a stimulating explosion.

when giving head, one puts pop rocks in their mouth. after a while the pop rocks fizz with the frothy spit and come out of the nose. Thus creating a pop rock volcano.
