What is a Yiddish cup?

No one knows, except apparently Neil Bauman-- after all, it was an integral part of his highly professional Cease and Desist letter (along with LOL). We do know it's possible to lose possession of it, however.

(Some have speculated that he actually meant "kopf", which means "head." "Yiddeshe kopf" is literally translated as "Jewish head", or "clever Jewish brain" figuratively.)
