An extremely pale Caucasian with skin so pale you might scream. The sour cream tanned individual reflects light from the sun making them dangerous to be around.

Their ghastly, pallid skin will send chills down the spine of the most courageous individuals.
Similar to the more common cream pie in which a man ejaculates inside of a woman's vagina. However, this cream pie results in the accidental impregnation of the woman.
