To pour coffee is to plug a drain with feces. Most often said in reference places such as public restrooms and water fountains. The term originated from how the water turns brown with shit. Waffle stomping is a similar activity, but more associated with a private setting.
Person 1: Dude, I saw someone pouring coffee in the water fountain.
