Jesus Christ on a cracker, I fucking hate people like that. When you have somebody else's property, you think you'd be extra careful with it, wouldn't you? /rage. (I'm sure I'm just bitter because I never got my copy of Assassin's Creed back from a former friend of mine who I'm never likely to see again. Twat. TWATWAFFLE.)
More on topic: actually threatening the guy sounds petty and is quite needlessly aggressive. Just remind him, "Hey, remember when you said you'd replace my disc that you lost?" If he just brushes it off, then just tell him that no, you are actually serious about this. He lost your game -- that you loaned him out of kindness -- and it's his responsibility to make up for it. If he doesn't acknowledge that, then that doesn't sound like any kind of "friend" to me. Tell him that and make it clear you aren't joking around, and be more careful who you lend your stuff to in the future.
CAPTCHA: enterprise spanking. Ooh, hello.
