Refers to the athlete Bo Jackson, used to describe someone who has all the potential in the world, and never meets that potential. Someone who blows it. May be an unfair association since Jackson did not blow his career (see Dwight Gooden) but was injured.
Someone who is an alien, they come and post up at parties, looking strange and different. they have beady eyes, and pubes on the top of thier heads. Believed to originate in area 51 after the captured aliens got loose. easy to befriend, but very strange species of alien.
hey man, look at that fucking bojacks just posted up over there, i wonder if he is going to warp home.
