aufruf

noun1

1. •
   (Judaism) An aliyah (Torah reading) made by the bridegroom, typically on the Shabbat before the wedding; a gathering at which this occurs.

   • At an aufruf I was at a few months ago, the groom's uncle did Adon Olam to the tune of "Rock Around The Clock". It worked amazingly well - it sounded like a one-man band on the bimah! — 2003
