a male pervert who enjoys starring at chicks in a nasty and perverted way. The origin of the name is from the Latin word "sperm whale". Later in history, the "uni-" was added to represent the word "unicorn" - an animal with a very large horn on his head (a horny horse). Thus the word "uni-whale" was born.
"Did you see the way he was looking at her? That guy is such a uni-whale!"
