My Body is Ready 

A phrase a virgin says when they're ready to knock boots.

Alternatively, a phrase someone says when they really like something and they want it NOW.

Sarah: OMG Jenni, the new Butt-Quake 6.0 comes out tomarrow. It's supposed to feel like having an 6.0 earthquake in your ass!

Jenni: Omg...My body is ready.
