When a person has a massive shit, and when expecting to spend the next half hour to an hour cleaning up one hell of a gastly mess, whipes their arse and realises there is no mess at all. Thus the Lord has blessed your hard efforts straining with a no mess joy.
I went for a banging shit, was a bitch to squeeze out, thought it was gonna be at least a whole roll to clean it but it was a miracle poo!

Get the Miracle Poo mug.
When you go to wipe your shitty arse after dropping the kids off at the pool, but discover there is no poo to clean up.
You were quick mate, are you sure you wiped?
Yeah mate, just had a miracle poo.
You lucky bastard!
