Butt Boner

the term used when you have to go to the bathroom so badly that you have surpassed "prairie dogging" it and now have a good two to three inches of turd protruding from the back of your shorts. Thus, you are sporting a "butt boner". OMG, is that a tail? Nope, just my butt boner. Can you point me to the nearest shitter?

shit, poop, turd, prairie dogging, take a dump, pinch a loaf, lay some brown pipe, cut some lumbar

Friend #1 - "I have to go to the bathroom so bad!"
Friend #2 - "Oh man, are you prairie dogging it?"
Friend #1 - "Past that dude, I am sporting a full fledge butt boner!"
