With raps, all over your head like Tweet

from Common – Aquarius Lyrics on Genius


His rap is too hard for most of his opponents to understand, most likely because he believes them to be unintelligent.
He uses the word ‘tweet’, to connect this into a bird metaphor, because birds are always flying overhead.

Referrence to the song “Oops (Oh My)” by Tweet, in which she sings

there goes my shirt up over my head
