Definition of the Day

Poo-Finger: an offensive odor found on one's finger even after handwashing, usually caused by diaper changes that require diaper rash ointment.  As in, "Unfortunately, I discovered I had a case of poo-finger while drinking a glass of water this morning."

Not to be confused with Sh*t-Finger, which is when you find actual feces on your hand because your kid needs help wiping and is really wiggly.  I think getting someone else's poop on you calls for cursing, if not out loud, at least in your head.
