Janie went "heels to Jesus" in chapter 15!
They fought on. “You done hurt mah heart, now you come wid uh lie tuh bruise mah ears! Turn go mah hands!” Janie seethed. But Tea Cake never let go.

Given, the “expression” Zora Neale Hurston is talking about is sexual intercourse. A very fun physical activity (from what I heard of course!) And what I believe Zora Hurston is conveying in this is that EVERYONE needs to release tension every once in a while. And most people would agree with me. It is not good to pent up all that stress on yourself, so it is best to release it somehow. Janie just found the fun way to!
