A few years ago I participated in a Purim Se'udah at which rounds of humorous poetry were written and then recited in a sing-song chant.
It was fun, and the tune rang familiar to me, but it was something I had never done before. I almost forgot what it was called, but last night I saw someone post something on social media about doing a Grammen at a Purim Se'udah yesterday, and I remembered that that's what our hosts a couple years ago had called it.
1. What is a Grammen?
2. What are its cultural and etymological origins?
3. When/how did it become a part of (some people's) Purim tradition?
