Similar to the ever popular kankle
, the hnee refers to the section of the leg where a knee once existed but now looks more like a hip. It is often the result of excessive fat from the upper leg/quadriceps hanging below the knee joint and resembling chunky inner thighs that slap together as one walks.
Person 1: "Hey, look at that lady chasing after her baby. She can't even catch a 3 year old!"
Person 2: "I know! Those hnees slapping together must be slowing her down."
Person 1: "If I had hnees like that I'd probably take a butcher knife to them."
