Coming from the word "Pedophile", meaning "Child Lover", Pedolaugh is a way of saying a creepy/pedophilish laugh. This laugh may occur when a person is being: odd, creepy, a pedophile or when a person looks at another person with lust. It can also be used once a person has said a creepy thing. A pedophile laugh either goes "Hehehe" or "Heeheehee".
