And I quote
Arthur B. Morgenstern ?:
"Even if you're disparaging yourself alongside the subject, it is prohibited. It doesn't matter if you look even worse than the subject, and it doesn't matter if you mention yourself first. Rabbi Pliskin gives some nice examples:
Ben and I both shoplifted when we were younger.
Nobody in our group studies Torah properly.
It is also forbidden to speak Lashon Hara about yourself."
