A phrase typically appended to the title of a sequel from a television or film series to mock its poor quality. The term was originated in the title of the poorly received 1984 dance film “Breakin’ 2: Electric Boogaloo”.
Amy: Did you see the last buzzfeed unsolved episode last night?
Charlotte: Omg, yes! It was so scary, poor Ryan.
Amy: Urgh, you're such a boogara, ghosts aren't real!
Electric Boogaloo can be appended to the name of a movie to indicate a sequel. This construction is somewhat dismissive of the original work and/or the idea of making a follow-up movie. The sequel may be real, planned, or imagined.
