Ooga ooga mooska means "I love you" in phony eskimo language.
Made famous in Hank Thompson's hit song, Squaws Along the Yukon, which peaked at No. 2 on Billboard's country and western chart in August of 1958.
Ooga ooga mooska
Which means that I love you
If you'll be my baby
I'll ooga ooga mooska you
Then I take her hand in mine
And set her on my knee
The squaws along the Yukon
Are good enough for me
