Yiddish cup 

A vague, indecipherable insult against Max Goldberg of YTMND.com by Neil Bauman of Ebaumsworld.com Possibly a misspelling of cap, in reference to the skullcaps worn by some members of the Jewish faith. This would make the phrase an anti-semitic ethnic slur

1. "Obviously you have lost posession of your Yiddish cup."
