Technique used in Mudvayne's "Happy?"

[FunkSlap89]

I recently saw Mudvayne's video for "Happy?" and I noticed that the bassist was using some strange technique. I listened closely and it sounded really cool. He only does it in the chorus, not the verse. If anyone is familiar with what i'm talking about, please educate me.

here's a link to the video:

saw this talked about awhile ago. in the chorus he is pretty much tapping that line.

There was a interview about that video somewhere where he said he was tapping it,

Edit : found it

Tapped harmonics. Fret the low notes, and tap them an octave higher. As it says in the BP interview, acts kinda like an octave effect.
