That means worldwide like a rising tide
I'm gonna subside and rise again like clockwork

from Big Boi (Ft. Ludacris & T.I.) – In the A Lyrics on Rap Genius

Meaning

Big has come up and will continue to rise to fame, just as the world experiences the scientific phenomenon of rising tides. Big Boi is going to consume everything in his path, just as water does as it rises in tides. A clever metaphor from ½ of outkast.

He’ll continue to ebb and flow (shine and then chill) just like these tides, or as the saying goes, he’ll do this “like clockwork” over his career
