I gotta be a big bang, gotta be
Never bottle me up in a probably, I wanna see or hear a "Yes sir, sir"
He’s being sarcastic here. The line “I wanna be a big bang, gotta be” implies that to be rich and famous and loved is a dream that everyone needs to pursue and is the only way to live. Hence he’s being sarcastic in saying this, as he continues to to so in “shovelling a big dig”, “I think big things”, “prime concern to earn thanks”, etc.
