Mrarr
The sound uttered when performing the act of cat feeting (putting the bottom of your foot on something or someone and pinching the object or person with all of your toes and the balm of your foot - like a cat would paw a surface for pleasure). Most often one would repeat the word over and over until the cat feeting session has ended.
