Ok, in the interest of being as accurate as possible, I listened to the song from iTunes on a pair of Hifiman HE-400S with the best DAC and Amp I had in the house and nearly blew out my ears from turning the volume up, trying to hear the passage. Even with all of those measures taken, it sounded kinda like the word was said, but I still don't feel it was distinguishable enough to determine that its not just confirmation bias.
I agree that the context seems like a nod to the Black Eyed Peas song, but it still feels like a stretch. I've listened to this song dozens of times and this is probably the first where I thought that slur is what was said.
