Scrape up you amateurs, babble on when I batter ya
Termanology boasts that he will make short work of dilettante rappers. In the most straightforward sense, he states that they will babble on aphasically as he batters them— as he either literally strikes them or figuratively beats them in a rap contest.
A more interesting interpretation is evident, however. Employing a culinary metaphor, he suggests that amateur artists are like left over brownie batter to him, only fit to be ‘scraped up’ and discarded post facto. This sets the stage for the next line.
An alternative reading might be “Babylon when I batter ya”, suggesting an apocalyptic scene of city-wide destruction like the fall of the ancient city.
Finally, it’s possible that ‘babble on’ is referring to the Big Pun-inspired technique that he employs in this verse: multisyllabic, internal rhyme delivered in quick monotone.
