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."

Boujee Upper Decker

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.”
