Attack Attack Vocal Effect?

Which sucking sound would that be? The reverse reverb (recording techniques 101 people...geesh)...or do you mean the music in general...since the term "sucking sound" equally applies to both.

I could swear I heard reverse reverb coming out of that kid's mouth the whole time. It was all suck. What rectal plugin do you think he uses?
 
In this kids defense, he can actually pull that song off in one take.

Are you serious? He's being drowned out the whole time by the music. You can barely even hear him except for in the momentarily passing moany parts, in which he sounds terrible; he deserves no defense or credibility. There's probably one simple, huge reason why he chose to drown himself out so much before posting the video...
