Stop mucking around and get your homework done
We spent the afternoon just mucking around in the garden
He was mucking around with some old tools in the shed
The kids were mucking around in the playground, laughing and shouting
Don't muck around with the settings if you don't know what you're doing
I don't have time to muck around; I need to finish this project
They were mucking around on the boat, splashing water at each other
She likes to muck around with her paints and canvases
He got into trouble for mucking around during the meeting
Let's not muck around; let's get straight to the point
Stop messing about, we need to get this done.
I am not going to muck around, I am just thinking.

Stop mucking around and get to work
Quit wasting time and start working
Cease your idle activity and focus
