To jack off in the kitchen while wearing a clown costume covered in cow's blood, while braying like a donkey.
1. John was gadoodling for hours last night, so I'm going to need some diet coke to get rid of the blood and cum stains on my tile floor.
2. I can't gadoodle with you tonight, my clown costume is at the dry cleaners.
3. Matt gadoodles so loudly, we have been asked if we own a donkey.
