Etymology

Origin of poop1

First recorded in 1375–1425; late Middle English pouppe, from Middle French, from Latin puppis “stern of a ship”

Origin of poop2

First recorded in 1735–45; earlier “to break wind,” probably the same word as Middle English powpen, popen “to sound or blow a horn”; uncertain if poop 3 ( def. ) and poop 4 ( def. ) are sense developments or parallel expressive coinages

Origin of poop3

First recorded in 1885–90; perhaps to be identified with poop 2

Origin of poop4

An Americanism dating back to 1910–15; origin uncertain; originally military slang; cf. poop sheet

Origin of poop5

First recorded in 1910–15; perhaps shortening of nincompoop

Explanation

Poop is a somewhat childish word for feces. When used as a verb, it means going number two. Poop is a very commonly used slang word that means feces and is far more acceptable than crap and shit. The only downside is that talking about pooping or poop sounds kind of silly. Still, no one will blink if you say "I need to take a poop" or "Go clean up your dog's poop!" There are a few other unrelated meanings — like the rear "poop deck" of a ship and "the poop", meaning the inside information on something.
