Back when you were sayin' "What in the world was that?"

from Lupe Fiasco – SLR 3 (Round of Applause) Lyrics on Rap Genius

Meaning

His rhyme scheme is so intricate with metaphors that people don´t even understand them which is why people are saying “what in the world was that?"
This works of course in general with Lupe Fiasco which lead to Soulja Boy saying

I don’t want to be super-Lupe-Fiasco-lyrical and niggas
don’t know what the fuck I’m talking about.

But it´s also referring especially to his latest song; a response to Kendrick’s verse on control and the prequel to this song: SLR 2, since a lot of people, including here on Rap Genius, called it wack. This is his response saying that we just didn´t understand it. The truth is people seem to appreciate the old one more now that times has gone by noticing his mockery of other rappers using their flows.

Line 1 to Line 4: Rick Ross
Line 7 (“get these heathens off”) to Line 9: Meek Mill
Line 14 (“Lu the boy”) to Line 18: T.I.
Line 19 (“Dinosaurs, I’m fine”) to Line 24: Kanye West, Eminem, Tyler the Creator, any of them can be heard.
1:45-1:57: Jay Z?
1:57-2:12: 2 Chainz?
2:13-2:19: Drake, but also is similar to the hook in “Bitch, Don’t Kill my Vibe” by Kendrick Lamar
2:20-2:39: Kendrick Lamar?
Line 46 (“He’s so crazy) to Line 49: Lil Wayne
