A person who lives and thrives off of the popular tv show "Lost". Lostaholics feed off of plot twists, unsolved mysteries, and time travel. Many Lostaholics attend LA (Lostaholic Anonymous) meetings, where they discuss previous happenings on their favorite tv show, and also make predictions of what is to come. Lostaholics are often found trading seasons of "Lost," re-watching old episodes, and researching hidden islands in the Atlantic.
