I always thought the line was "mad punk f***ers, which is also a better rhyme for "suckers,". I was hoping to find an answer here, but there is no consensus, so I tried something else -- I went to youtube and found a video of Joe singing it live (https://www.youtube.com/watch?v=DZ3NDP-Qiak). In that version, it definitely sounds like "mad punk rockers." There's also a closeup of his face at that point in the song, and the movement of his lips also corresponds to those lyrics.
Of course, he could have changed it for the audience, but I'm going with "mad punk rockers."
