What does mucking mean?
Mucking usually appears in the informal British expression “mucking about,” or its North American equivalent “mucking around.” It means behaving in a careless, idle, mischievous, or unhelpful way, often making a task unnecessarily difficult or delaying it. The expression is usually mildly critical rather than seriously hostile: telling someone to stop mucking about means that their behaviour is frustrating and that they should do something useful. In a less common but traditional sense, mucking refers to doing dirty work, especially cleaning animal waste or working with soil. Mucking can also be used informally as an intensifier, as in “mucking brilliant,” functioning as a softened substitute for a stronger swear word. As a verb form, mucking is the present participle of muck. Its most recognizable use is conversational rather than formal, so it is uncommon in formal writing, though the underlying verb is ordinary and broad in meaning.
To behave carelessly, idly, or disruptively, especially in the expressions “mucking about” and “mucking around.”
"We cannot complete the release while the team keeps mucking about."

To perform dirty work, especially work involving manure, waste, or soil.
