It's a pretty cool song I came across when browsing around, and I think it's gonna pump up some axe into the NUS roda =D You MUST listen to it. Yeap, you must. Go on, I know you want to ;p
The chorus just goes 'Nego nego nego nego!' which means, 'Give it give it give it give it (to him)!'
You can see the lyrics on the youtube video (karaokeira, anyone? ). Thing is I'm still looking for the full meaning. Meanwhile, enjoy!
