The rolling on the floor laughing emoji is used for a stronger kind of laughter. It suggests that something is so funny the person can hardly stay composed.

How it differs from tears of joy
Both emojis mean laughter, but this one is usually more dramatic. It fits wild jokes, absurd situations, unexpected replies, and moments that feel over-the-top funny.
