mad minute
A mad minute is when soldiers in the 1700s tried to reload their muskets so fast they looked like they were having a nervous breakdown. It was like a competition to see who could reload the fastest and scream the loudest.
'I reloaded my musket in 30 seconds and I won the mad minute.'
'I got distracted by a dog and failed the mad minute.'
'The mad minute was the worst part of the battle. I was crying.'
