The term generally refers to the use of improvised or manufactured urinary drainage systems (commonly called "piss tubes") to avoid stopping a task or leaving a vehicle.

(Looking for how portable sanitation is engineered for remote workers?)

Improperly cleaned systems are breeding grounds for bacteria, leading to UTIs or skin irritation.

Used by people living in small vehicles where installing a full bathroom is impossible.

On platforms like YouTube or TikTok, creators sometimes use the "gross-out" factor of these setups to garner views, framing it as a "hardcore" or "minimalist" lifestyle.
