Some people ywap when talking on the phone.
Not really what you were looking for, but I remember the word from the movie. The following is an excerpt from an interview.
Ethan Hawke, HITFIX interview, August 31,2014:
"Somehow it's like you're not breathing; you're being breathed. And the first time I ever had that feeling was with Robin Williams. We had this scene, "I sound my barbaric yawp over the rooftops of the world." And it's etched in my brain as him standing in front of me writing "yawp" on the chalkboard and he said, "Todd doesn't think he has anything of value inside him." That scene is pretty much shot in one take. It's cut a little bit but Peter [Weir] shot it on a steadicam spinning around us. I remember Robin hugging me after that scene was over. It's a high I've been chasing the rest of my life. I mean the last 25 years since then or whatever.
It's also something that's absolutely heartbreaking and tragic about the person who taught you the expression "carpe diem," taking his own life. You know, there's something really terrible about that. But he was always – for every great high there is a low. And he was a person who experienced tremendous personal highs. I mean being around him you felt the epic swings in his state of mind. Even at 18 I was with it enough to sense those. So I feel for him and I feel for his family."
RIP Robin William
Yawping leads nowhere?
