I'm gonna second that
When you're about to clean up and someone steps in like they're your boss and says 'I'm gonna second that!' just to mess with you.
I was about to wipe the table and my friend said 'I'm gonna second that!' and sat down.
I was cleaning up and my boss said 'I'm gonna second that!' and left a mess.
I was about to put the plate away and my sister said 'I'm gonna second that!' and took the plate.
