An extension of the commonly expressed 'yuck!' for something that tastes bad or is gross. The 'o-la' is meant to soften the word, or make it a little bit cute sounding.
Would you like the rest of my hot dog? Yucky-o-la, I don't like hot dogs.
Give me a kiss. No way. Yucky-o-la. Your breath is so bad.
