[Dragon Ball Z] Can I shoot energy blasts from anywhere on my body?

I am a saiyan on the planet Vegeta. Yesterday I saw a saiyan shoot an energy beam from his feet. I have a party to go to and it would be really funny if I could shoot my signature Cesa Sala energy blast out of my butt. Is that possible?

Probably as a Saiyan has been shown to shoot energy out in a sphere around thier body.  The hands just make a convenient focus point.  We've seen the eyes and mouth also used as a focus point.  You'd just have to train using your butt as a focus.
