It is mostly used as a greeting or a goodbye. Poop poop is a noun describing someone in your life. So it takes the place of....buddy, pal, dude, brother, sister, father, mother ...etc.
So instead of "Hey Buddy" You would say "Hey Poop Poop" And it is understood that it is meant with a little splash of love.
