Welcome, but you might be in the wrong place. There's no such thing as "play money", only "money", and how much of it you choose to spend on "playing" shouldn't depend on where it came from.
Well done, your investments produce more money than you need - but I'm sure you didn't get to that position by taking your own advice to give away any money that you weren't expecting to have. It's not like there aren't going to be unplanned expenses, too.
What you're suggesting is "don't invest it, spend it!" which is kind of the exact opposite message of this site. Also, you aren't going to fool anyone by putting the "investment" label on something that is obviously spending.

I vote shove it straight into an index fund. Market crashes happen, but anything predictable is already factored into the price today; besides, it hardly matters what happens in the short term.
