A term meaning nothing at all but what you want it to. Often pronounced sarcastically and overdrawn and without the middle "mu". Originates from a Saskatoon speed skating meet where the legendary Greyeyes wanted a "mumuhug." The word is also believed to have been used by Amanda Bynes on the Amanda Show when she did skits portraying a mentally challenged little girl with an affection towards yogurt.
