A derivative of the "awkward turtle". It is when one assumes a squatting position and then proceeds to make sounds familiar to that of a pregnantwalrus (sounds something like this: "urgh urgh urgh urgh urgh!"), whilst waving their arms by their wast. Unlike the turtle however, it is used to create socially awkward situations, rather than emphasize them.
When a person enters the room, everyone does the awkward dolphin to make the newcomer feel awkward for a few seconds. Then act like nothing had happened.
