My girlfriend/live-in lover/partner in crime and I have an understanding: whenever one of us loses an argument beyond denial, thoroughly pwned, then he/she must open the front door (or the back; which one is not important) and shout at the top of their lungs, "HEY, Y'ALL! SHE WAS RIGHT AND I WAS WRONG!"
