wankeroo
like jacking off or wanking, it's basically a waste, as in a waste of time and effort. Doesn't amount to much, it's basically just junk.
Much of the popular music in the fucking PC 90s and afterward, particularly this emo crap simply  sounds like and says the same old thing, like "Ewwwwwwwwwww! You fucked me over this way, you fucked me over that way! You ran over my pet hamster with your Radio Flyer wagon when I was 6! Wah! I'm traumatized. Gimme some heroin." Most entertainment today is pure wankeroo because it's so cliche-ridden, formulaic, disposable, cookie cutter, without passion and unoriginal.
