Strange celebration

I noted with surprise and dislike Tabraiz Shamsi’s Shoe Dialing celebration every time he took a opposition’s wicket. during 1st 20/20 cricket match dated 10th April 2021 between Pakistan and South Africa. Every time Shamsi took a wicket , he took off his shoe and put the lower side of it at his cheek and ear to as if he is talking on phone . What does this celebration means ? I don’t know but what I am sure is this was a not good activity to see while watching international cricket especially with family .
