When you're doing anal with your girl and she has diarrhea but you keep pounding on it making slapping noises and its splashing in your face but it's dark and you just think it's more wet ... you sir have been chillidoggin
My girl and I were chillidoggin last night , excuse the smell
Open playboy night is where you are fucking some ugly chick that and you have an open playboy on their back imagining you're fucking the playgirl you are looking at in the magazine.
It's open playboy night on your back night.
