When Harrison was little and he had a poopy diaper, we would say ooh did you do a poopers? So the word poopers was in his vocabulary from an early age. Then when they got really stinky, we added the word, so it became a "Stinky poopers". And that's still the words Harrison uses, for No1 and No2! Now, had we thought about it, we would have chosen our words more wisely, these words are fine for at home, but while out?
In line at Kroger?
"Stinky Poopers Mummy!"
Not so much.
Maybe will Allister will will call it going potty instead ;O)
