crossed the line

Violated a boundary

Crossed the line means went beyond acceptable limits—violating a boundary of behavior, decency, or propriety.

The line is imaginary but understood: That joke crossed the line.

Someone who crosses the line has done something offensive, inappropriate, or unforgivable where before they had not.

The phrase often marks the moment a situation shifts from tolerable to intolerable.
