Yorkshire Breakfast
When an obese female sits on an open window sill while wearing an "oversized" T-shirt, that only appears as a a normal T-shirt due to her size, and promptly displays her vagina to everyone within the room. Often having pubic hairs branching out in a formation similar to that of C'Thun from World of Warcraft.
As I was walking up my stairs, my roommate had her disgusting Yorkshire Breakfast out in the open.
