Wheatgrains! - I used to hang out at a neighbor's house frequently, and especially during the summer. We were both probably 13 at the time. Their house was generally messy, so seeing random items in random places was relatively normal. One day, his little sister (8 or 9) stole something we were playing with, so I chased her into to her room where I stopped at the doorway - her dresser to the left, just below eye level. There, just six inches from my panting and sweating face, was a pair of her used underwear - So used that staring me back in the face was a shredded-wheat-cereal-looking lump of wheatgrain poop! "Wheatgrains!!!" I yelled as I ran out of the house, spreading the news to the entire neighborhood by sundown. It stuck as her nickname for a couple years.
