A poo man chu is the poo mustache one gets when giving an rj to a girl that does not know how to wipe well.
I was lik'n this bitch's rusty bucket the other night, and when I was done I smelt poo on my lip, so I checked in the mirror and realized that ho gave me a poo man chu.

The act of unknowingly performing a mustache ride in reverse and suffering the physical consequences and repercussions of this task, hence, a goatee/mustache full of dingle berries.
I totally thought that cody was giving his sister a full frontal stache trip but that mofo came out with a poo-man-chu.
