Pa-Jaba-Jaaaa
A fancy way to say 'I showed up,' but also sounds like you're screaming in a haunted house.
Pa-Jaba-Jaaaa! I came to the party and I'm not leaving! (He brought a karaoke machine.)
Pa-Jaba-Jaaaa! I came to the fight and I'm bringing my brother!
Pa-Jaba-Jaaaa! I came to the game and I'm gonna win!
