in fact not three sounds put together to create a vynal scratching effect, but the noises made by anybody that thinks they will sneeze but never quite make it. The oh is a display of disapointment because not being able to sneeze sucks. With the oh usually being slightly more delayed
i think im gonna ... wa-ah-oh.
three sound which put together allow you to vocal scratch. different variations of the sound and order allow other words to be included for 'vocal scratching
wa-ah-oh -wa-ah-a-oh -wa-ah-a-oh -weh-wi-wicked
weh-wi-wicked-wo -weh-wi-wicked- weh-wi-wicked weh-wi-wicked-wo weh-wi-wo-yo
