Most of us admire our own pets or different other animals for their graceful beauty. An animal is more prone to different mistakes than any human beings and when they commit any mistakes, there are few typical expressions which are found on their faces.
These expressions are commonly known as herp-derp expressions. Sometimes you cannot resist yourselves from laughing if you see your pet with funny expressions but the derping animals are those who love to keep their tongue outside their mouth. Especially they do it only after committing any kind of mistakes even if knowing that they should not have done this. via boredpanda
