|1.||Leaving an Orphan|
Usually performed by defecating in someones toilet other than your own. Then you carefully leave the bathroom and look for somewhere else to wipe. The next person in the bathroom is stunned to see the "orphans" in the toilet. May also be tastefully displayed by first lining the toilet water with carefully folded toilet paper, thereby ensuring your orphans won't drown.
After the golf game I poached in Dr. Hook's bathroom and left an orphan for him.
