The biggest comboniation of a Jew and a Nerd ever. A rosenbloom is often found sucking on the cock of a powerful person such as a Rabbi or Michael Jordan
Yesterday, I saw a rosenbloom watching Star Wars while reading from the Torah.

A Jewish man-whore. A Rosenbloom might be kosher, but their meat gets around.
That guy is such a Rosenbloom, he's tapped every girl at our Jewish Community Center and all the chicks in the theaspain club.
