horn puppy
A horn puppy is pretty much the same as a horn DOG, but a little more specific. It is used to describe someone who is perfectly sweet and charming but only wants to get in your pants. The difference between this and horn dog is that the horn dog doesn't bother being sweet or charming. It can also be defined as someone who uses the dumb "puppy-dog look" and licks their lips in a provocative way simultaneously.
