lace the fuck up
A dumb way to tell someone to get ready for a beating, like they’re about to fight a giant chicken.
My gym teacher said, 'Lace the fuck up, or you’re running laps for the rest of the year.'
My neighbor screamed, 'Lace the fuck up, or I’ll throw your lawn gnome in the trash.'
My cat hissed, 'Lace the fuck up, or I’ll claw your face off.'
