Did you mean that ‘jackass laugh’? (Tune into radio shockjock shows for examples.)
One year in Bill Hickey’s acting class we had a male student who was extremely crude, a complete boor, he even had that sociopathic jackass laugh. But in his acting exercises and scenes he would put on incredibly emotionally nuanced, fine grained performances. Even then I realized that that persona was his true self. I now believe his father was a sociopath and that he had equated maleness with sociopathy. It seems he had gone into acting to keep his soul alive.
