A word signaling simultaneous frustration &
confusion. It's uttered after some event that frustrates & confuses, and you
just can't let the
moment pass without some kind of comment.
Curly Howard (The Three Stooges) frequently said "Sheeesh!" after
something didn't operate the
way it was expected to operate, like a telephone. Or when he was slapped by his
brother, Moe, for no apparent reason.
