URB..URB. URB.......

The sound may be a unique one. Actually, when we drink coffee (I'm sorry Kaapi) we make this sound. Particularly, when you drink a filter coffee , you hold kaapi tumbler in one hand and the newspaper in the other hand. The situation is indescribable . This URB sound has become a brand of a leading coffee maker which is nothing but BRU (just an ulta).
