-a hug using the legs. usually occurring because one cannot or does not have the use of his or her arms. the leg hug is performed while in air rather than sitting down, in which case, would make the leg hug akward. the ideal leg hug is one that is performed while being lifted by another person, and hugging another across the room. the use of arms and legs at the same times makes it a backpack hug and thus is not acceptable.
