A "Jackassaniacal (JAK-ASS-A-NIAH-KAL)" person constantly loves to go the extra mile to be not only annoying or a nuisance,but makes sure that everyone around them is not only uncomfortable around them but goes out of their way to act like a selfish baby or jack ass simultaneously while being a pain in the ass at the same time.
