Back to the SH thing...from Every Goy's Guide to Common Yiddish Expressions by Arthur Naiman, some good SH words.
"Shicker (SHIK-ur)
Drunk.
A drunk.
Shkutz (shkoots)
Derogatory name for a non-Jewish man
Shlemiel
Jerk, particularly a nerdy sort of jerk.
Yiddish has more words for this concept than any other ten languages put together. Here are just a few of them: kuni lemel, nayfish, nebbish, schmuck, shlemiel, shlep, shlepper, shlump, shmageggie, SHMENDRIK, shmo, shnook, yutz and zhlub. There are minor variations between these words, of course, but they all indicate ineptness, lack of common sense, lack of physical grace and sex appeal, a quality of hopelessness and -- how shall I put it -- well, shlumpiness."
Then there's also shlimazl, shmutz (meaning dirt - a personal favorite word of mine), shmata (meaning rag - another favorite - most often used to insult someone's dress, like "I like what you've done with your hair, but why on earth would you wear that shmata outdoors!")
