She had a sexy part that was just rrrnnnhhhl

The tragic thing is that when he succeeded in integrating her, she had total amnesia for her entire life, and was a drip as far as I could tell. She had these great parts. She had a sexy part that was just rrrnnnhhhl Another part told jokes and was really corny. Another part was very shy and coy. But when he "cured" her, she had amnesia for her entire life and she had none of the resources of any of those parts. She was just dull.

Hello, the above is from Frogs into Princes by Bandler and Grinder. They talked about a case of multipersonality of a woman. What does "rrrrnnnnnnnnnnnnh" mean? Thanks!
