When two people connect their assholes with a plastic tube, preferably clear. They take turns pooping, sending eachothers poop back and forth until either the skyway is full or their bowels are empty.
Think of a bustling metro skyway, except instead of business people passing through, it is human excrement.
An area mistaken for the hood in the previous definition. It is a generally low income neighborhood, but its actually an OK neighborhood. Plenty of middle class families living here.
Person 1- You live in Skyway??? Isn't that the hood?
Person 2- Nah, skyway isnt that bad.
