Headbutting his jocks

When a massive big Grogan is knocking on the back door, It's headbutting your jocks.

Bill ran in urgency to the rest room after 24 chicken nuggets and 3 red bulls for breakfast. He was on a tight line if he could make it or not after his tummy got full of all that junk.
He knew if this massive Grogan that was headbutting his jocks wasn't gone from his sphincter he was going to have a mess on his hands after the exorcism of his anus took place in the porcelain throne room.
