An Irish phrase. Another way to tell someone to “wise up”.
To stop being so ridiculous and to come back down to Earth. Can also be said in an affectionate way, for example, when someone is being hilarious and ridiculous and you don’t agree with what they’re saying; Irish people’s tones will tell you the difference.
“I’m too sick to go to school...”
“Are you dying? No! Didn’t think so, catch yourself on and get out the front door.”

“It’s raining mammy and that means Jesus is crying.”
Hahahahahaha catch yourself on ya eejit, it’s raining because it’s raining!”
