Yak Legs
A person, usually a guy, who has insanely thick, dark, coarse body hair. Particularly on the legs. Sometimes a person whose nickname is yak legs runs track in high school and must wear long shorts or pants to cover up his scary legs. He also thinks that he is a star at whatever he does when it comes to activities in which shirts are optional, but everyone else sees through this and is just plain creeped out by it. Usually a small guy with a tough-acting facade. Doesn't know how to take a joke or appreciate true humor. You know who you are!
Look at that kid with yak legs, he needs to shave his entire body....like right now!
