The time at which the clock strikes 1:40, if you are not in doggy you thinking about doing doggy. Basically you think about sex during the late hours of the night. I.e “it’s dog hour”
You bring your dog out for a walk and come back inside, where, lo and behold, there’s a huge poopy stuck to the dog’s ass that never came off outside. You can’t take it off with dabbing with a paper towel. You gotta shower off that dog butt. How fun is that?!
Oh no, my dog has doggy poop butt after the walk today. What the hell am I gonna do. It smells so bad. Aaargh! Puke puke.
