Possibly the worst invention in history. The double decker outhouse is, quite literally, two toilet stalls stacked. Although this structure conserves space, it is completely impractical and downright messy.
Bottom stall occupant: What's that creaking?
Morbidly obese top stall occupant: ... I think the floor is caving in.
Bottom stall occupant: *Sigh* ... who in their right mind invented the double decker outhouse?

Taking a shit in another person’s essential oil humidifier without telling them. Usually as a form of retaliation in which a classic upper decker just won’t cut the mustard.
“I know I had to get back at that twat waffle after he cheated on me with my sister. So naturally I left him a boujee upper decker when I moved out.”

A sexual position (FFM) where two women are stacked atop one another both doggy-style and faced in the same direction, so all the male sees from behind is two pussies atop each other, hence the "double decker" pussy.
"Man did you see that Peter North vid with Asia Carrera and Jenna Jamieson? It was fucking nothing but double-decker pussies the whole first scene!
