Sledging is part of cricket and some examples are better than others. Sometimes it rebounds on the bowlers who deliver the words.

Former Zimbabwe cricketer Eddo Brandes once had a colorful exchange with Glenn McGrath.
Brandes: “Because every time I “f**k” your wife, she gives me a biscuit.”
In an interview, Indian bowler Sreesanth said: “He (Lara) defended a ball with an exaggerated back-and-across movement and I just stood there and murmured my disapproval. Next ball he was beaten and I said, ‘is this the King Charles Lara? Who is this impostor, moving around nervously?
“I should have kept my mouth shut for the next ball – mind you, it was a length ball – Lara just pulled it over the church beyond the boundary! He is a true legend.”
I don’t have much personal experience of this. In the under 12s I was once heckled by a wicketkeeper who made abusive remarks I can’t remember while I was facing to bat. My response was to pull the bowler up half way into his run-up, which of course they hate.
It worked.
its okay with sledging. but it shouldnt be shown to public.it should be kept within players only.
