An abnormally sized defecation. The size of the defecation may be relative to your own size and stature. It is either: (a) a defecation that hurts your anus, making it feel as if a tear has bolted its way up your rectum; OR, for the more adventurous at heart, those sticklers for authenticity and bragging rights--(b) a defecation that pokes it's head through the surface of your toilet water and stares right back at you.
Why my oh-my, my ass is on three sorts of fire; I must have dropped a Brompton! (looking at the beast below him or her) well, I say, there's its head and neck craning from the depths of my toilet water--it MUST be a Brompton! I shall call my friends and let them know of this discovery!
