habitual line stepper
A buddy who takes things way too far. They cross the line with shots, beer, and sometimes a full-on wrestling match.
He crossed the line at the bar and started a wrestling match with the bartender. I had to break it up with a shot glass.
She crossed the line at the party and tried to drink the punch. I had to stop her with a plate.
He crossed the line at the store and tried to take the last candy bar. I had to drag him out by his belt.
