double decker outhouse 

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?

Lower Decker

The act of defecating in a urinal. Commonly done in a old fashioned urinal system in which the water does not flush, leaving a wretched stench and a very unusual surprise for any unsuspecting person who wishes to urinate.

"This school dance sucks!, i'm going to take a lower decker in the bathroom."
