Used in twitch chat when the streamer is UNAWARE or if he DOESNT KNOW what to do next. It's simply Pepe the frog holding his laugh in and trying not to say anything.
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".
Pedophile to random boy : "You have nice eyes... Hehehe"
