From the early 90's Pirates of Dark Water cartoon. Used by Ioz, Ren, and Tula. An exclamation meaning something along the lines of "holy crap" or "oh shit".
"Chunga Lunga! Bloth is off the starboard side! Ruuuun!"
"Dark water dead ahead, and Bloths on our tail, Chunga Lunga, how will we escape this one!?!"
