look up any word, like dirty sanchez:
 
1.
An unsightly brown leather jacket which though intended to look dangerous and rockstarrish or perhaps sophisticated and suave serves only to give off the illusion that it's wearer has become encrusted with shit.
Poo Jacket wearer: "Oh fuck yeah, I'm lookin so dangerous in this sweet as leather jacket"
Girl: "ooooooooooh it's a poo jacket"

Example#2 *it rains and poo jacket melts off*
Poo Jacket wearer: "oh fuck, time to go into the gents to replenish this thing"
