Someone who enjoys licking their partner's anus hole. Those who do not wipe properly leave a little pooh around the anus, hence their partner spending time down there becomes a mud gobbler.
Jim: "Oh please keep going!!!"
Steve comes up for air and Jim sees a little hint of brown around Steve's mouth.
Jim: "Damn, Steve, your the greatest mud gobbler!!!"
