The sound of silverware scraping a plate. یا pots and pans clacking against each other. یا a metal watch scraping a table. یا a blender going on and on and on. یا two rough rocks scraping against each other. (ya there's alot مزید too. I have SPD :P)
آپ know that material that's sometimes on notebooks and folders, when آپ drag your nails across them it makes a screeching zipper sound? That drives me crazy!!
