0 a mistake that completely spoils something:
Indeed, one of the main architects of the bureaucratic muck-ups is to wind up the debate tonight.
In 2003, three police cars were dispatched to the school when muck-up day activities went wrong after carloads of youths wielding baseball bats and wearing balaclavas arrived at the school.
What a "muck-up" our defences were in.
However, the fact is that they have made a muck-up of it and, as a consequence, it needs to be withdrawn.
If this muck-up had been made by one of the public corporations we should have seen it in the newspapers for months.
