We (re-)invented a terrible game here at work. It's straight out of third grade:
Whenever somebody says something, evaluate whether it would be amusing to take the last word or several words of their sentence and say them back in an accusatory way.
Josh:"The humidity makes the air feel thick."
Me: "You're THICK!"
Josh:"Seriously, that's getting kind of annoying."
Me: "You're ANNOYING!"
Yes, it's infantile (you're infantile!) and stupid (you're stupid!), but it's also totally fun. Try it today!
