In this clip of the movie 'Moana', at 13 seconds into the video, Moana says "Teach me to sail," to which Maui makes a sound of derision or contempt by blowing through closed lips without using the tongue.
What do you call Maui's act of making this sound?
Is it called "Bronx cheer" or "blowing a raspberry" or something else?
As I understand it, both Bronx cheer and blowing a raspberry would involve the use of the tongue as well as the lips. If so, Maui's act is not exactly Bronx cheer or blowing a raspberry, because he didn't use the tongue at all.
Is there a separate term for making the sound only with the lips? Or can Bronx cheer or blowing raspberry be used to describe the act of making such a sound only with the lips?
