Milk mouse came from the famous ancient philosipher by the name of Moe Jiller. We all know Moe said it best when he saw a hideous fat retarded girl and screamed "ahhhh milk mouse."

This also, in effect, later on in the 20th century gave nerds and white trash people that would actually have sex with their virginal bodies.
