cryptoscopophilia
The urge to look through the windows of homes upon walking past them. Usually done for sexual satisfaction/curiousity reasons.
My! I once recall walking infront a curtain-less window and; being the cryptoscopophiliac that I am...I took a gleek and there was this hairy man bonking his wife senseless! I saw from her body only the wildfire bush of her na-na. Grossest!
