Identify the soundbite: end of "We Will Rock You" remix

At the end of a remix of We Will Rock You, there are two sound-bites.

“What does it all mean” and
“This stuff is really fresh”

The second one is the one I’m interested in - it sounds like something I should know, but can’t place it.

Queued up to the two soundbites.

This stuff is really fresh is from this, right at the very end…

Everything I’m seeing online says “What does it all mean” is from this clip (around 2:40), but it sure sounds a lot different to me.
