Hit it!!

I'm sure most of us have heard the phrase "hit it", right? So I'm not going to bother explaining it. But funny story to share of course.
So my soon to be sis-n-law Jen was thrown a bridal shower by my mother-n-law Tracy Saturday. One of Jen's friends brought over these cute paper flowers in a vase that everyone needed to write some advice on for the bride. After the shower, I offered to drive some of her new things over to her apartment down the street and Tracy rode with me. She was holding the vase of advice flowers and started reading them as I drove. Most of them had all the crap you'd expect...don't go to bed angry, pray together, be patient...blah blah blah. And then she read, "Hit It!". To which she said, "Hit it? That doesn't even make sense."
I about DIED all while suppressing the urge to burst out laughing. I wasn't about to school my mother-n-law in slang 101.
