Need a Curse Word from the Past

Let’s say it’s 1890 or so (plenty of wiggle room). You’re a young man from a wealthy family, but you’ve been disowned. Good schools, but since then you’ve run with a pretty coarse crowd. Now you are under extreme duress at the hands of some guy who is totally beneath you.

“You ______!” you cry out in anger and frustration. If there were ladies present they would drop their porcelain teacups and faint dead away. Men would take umbrage, while servants scurried about hoping not to be noticed.

Please help me fill in the blank. If there’s a particularly choice word from an earlier time, that’s fine, too. 1900 is about the latest, but even as early as 1700 would be cool.

Thanks!
