A "One-Six" is a code-phrase used by guys who decide to pee outdoors when there are more than enough opportunities to do so within a home or establishment. Peeing outdoors is one of the great advantages of being a man. The term was jointly established by two cousins who were very drunk one night and has since spread throughout the American South. While sitting on the back porch, one cousin stood up and made his way to the edge of the back porch and began to pee. The other cousin asked, "Jeeze man, does she know how much you pee off her back porch?" "Nah, man she only knows about it one sixth of the time." "AAHahah... the ONE-SIX!!!"
Wife: "Hey babe... Wha What are you... Damnit Hank, ANOTHER One-Six!!?
You: "Don't hate me cause I can, Baby. Don't be jealous; God made us all the way we are."
You stand up at a party and head for the front door:
"oh, you have to pee? Someone just walked out of the bathroom."
"Nah, its feels great outside. I'm just gonna One-Six it."
