When you try and write the sound of a person laughing, the standard "haha!" does not always capture the true sound and meaning. Different laughs have different flavors. For the benefit of world peace, here is a list of written laughs, and information on those subtle differences.
| chortle | gleeful chuckle, chuckling and snorting. Ususally designated as a description of a weird laugh, but a chortle can be a laugh you make when you REALLY enjoy something. Often used in British comic "the Dandy and the Beano" or "Beano book", e.g. Dennis the Menace's annoying habit of guffawing at his own actions: 'Ha ha! Look Gnasher! Chortle!' |
| chuckle | quiet laughter, more through the nose, can be nerdy |
| guffaw | belly laugh, hearty, boisterous

| ha ha | absence of an exclamation mark can be a hint of sarcasm, or indicate a polite, but unenthusiastic laugh, though not always. |
