laugh one's head off

Cackle without stopping

To laugh one's head off is to laugh extremely hard, uncontrollably, or for an extended time: We laughed our heads off at that movie.

The exaggeration suggests laughter so intense it might detach your head.

Like similar expressions (cry one's eyes out, scream one's lungs out), it emphasizes the physical extremity of the action.
