Alpine,
What does schmuck (and putz for that matter) mean in german? In yiddish, which is what is used in the usa, they are both nasty terms for male genitalia. Most people think it just means "jerk" or something like that. But it is a definite curse word in yiddish.
Sorry for going way OT but when I looked at the website you suggested many words ended in schmuck.
Bikemomma - cool sites!
