Originally "wakka wakka wakka" as uttered by Fozzie the Bear of Muppet fame. Fozzie wanted to be a comedian. Unfortunately, he was terrible. The threefold utterance was part of Fozzie's act. The shortened version has gained usage as an expression of delight, exultation or lust (sometimes all at the same time).
Fozzie: !Ahhhhhh! Wakka-wakka-wakka! Thank YOU, thank YOU, and thank YYYYOU!!
