Hendrik, he was asking you to explain, to elaborate, etc. on what you wrote since he did not understand what you wrote. He is asking you to clarify. When you wrote:
"Do you know that WCK doesnt have kick as how kick generally define?"
You were unclear. How do you think a kick is "generally defined" [sic]. And how do you think that is different from a WCK kick?
Here's two "general definitions": to strike out with the foot or feet, and to strike with the foot.
