To utter a series of words or sounds in musical tones with the purpose of singing an entire song when not all the words are known.
In the song "I'm a Loser" by Beck: The words are "Soy un perdidor, I'm a loser baby, so why don't you kill me" someone who is hemasobbing might sing something like "oi ooh hairdressor"
