Mad Tested.
When you tell your significant other you did something that you're thinking of doing soon but haven't actually done yet so you can see exactly how mad they will get when you actually do it. Should they get REALLY mad you pretend it was a joke and don't do it.
Mad Tested. = Dude I totally Mad Tested my girlfriend last night and she wasn't all that mad so I'm going to skip that boring thing with her and her family this weekend and meet you at the bar instead.
