What does the Yiddish word putz mean?

Answer 1

fool or idiot--someone behaving in that fashion.

Correction:

The literal meaning of 'putz' is slang for male genitalia. The English equivalent is d*ck.

Though it's original meaning was equivalent to calling someone a penis, which in the old country was a great insulting expletive.

With today's youth it just means the same thing as the American insult, Dick, like your being a dick buddy, or your being a putz buddy.
