LOL stands for "Laughing Out Loud." It's the more common and widely recognized term, used to indicate a chuckle, a good laugh, or even a burst of laughter.
XDD is less common but still widely understood. It's an onomatopoeic representation of laughter, mimicking the sound of someone giggling.
Here's a breakdown of their meanings:
* LOL: Used for a wider range of amusement, from a light chuckle to a hearty laugh.
* XDD: More often used for a lighthearted giggle or playful amusement.
Both terms are often used in online conversations, text messages, and social media posts. They are generally considered informal and are not appropriate for formal settings.
Remember that the meaning of these terms can be subjective and depend on the context of the conversation.
