Doody Balls happens when you wipe from back to front and shit residue collects on the back of your balls, which in turn creates balls that smell like doody.
I let this chick go down on me after taking a wicked crap and I had a foul case of doody balls.
Sometimes while taking a shit, your penis touches the inside of a disease laden bowl. To avoid this it is necessary to push your penis and balls further into the toilet. Then you accidently shit on your balls.
The other day I used a public restroom, and I gave myself a severe case of Doody Balls. My balls smelled like shit for days.
