The act of defecating directly in someone's freezer. The result of this poopsicle predicament is whether to chip away at a frozen browntain or unplug the unit and deep clean because everyone knows you're the germophobe you know you are.
Found out Lou slept with my girlfriend and never told me so I left him a polar decker while he was sleeping so it froze solid before he found it.

A mountain of human feces. Either in an urban environment or in nature. An uninterrupted pile with no indication of what was used to wipe.
Walking down Bourbon St. I encountered a browntain in the middle of the street. Miraculously it remained undisturbed as the crowds of people walked by.
