"I own the property of your wife upon which you stand."

You should probably get off. That's gotta hurt.

It means: 'I have told your wife what sort of stuff you're into', with an obvious sexual/romantic connotation.

Believe me, I'm German. Hope it helps.

I've told your wife what you're into...

What are you reading? it sounds quite interesting, i hope it's not just what's happening to you

Not convinced the last part is correct German, but the first part is:

I've told your wife......(maybe 'what you're up to'?)

i have your wife on what he tells you stand

I HAVE YOUR WIFE TELLS ON WHAT YOU ARE!
