Here are a few expressions that use the word 'march' Remeber that 'march' is the name of a month, a type of uniformed walking (imagine a group of soldiers walking), and also a group of people walking in a public area to show support or protest towards something:
To be crazy:
'I was just speaking to Tom. That guy is as mad as a March hare! He has the craziest ideas.'
To be different from the rest; to do things in your own way:
'Everyone except Sarah went to the bar. She marches to the beat of a different drum'
Usually the start of March is wet and cold (lion), and the end of the month is mild and pleasant (lamb):
'The start of this month was so stormy, and now it's lovely. March really does come in like a lion and go out like a lamb.'
To do something before someone else does; to beat them to it:
'We stole a march on the competition by winning that big government contract.'
To march in protest or demonstration against someone/something:
'The protesters marched against the unpopular new law!'
