The multiple "lols" might signify:
* Stronger laughter: The more "lols," the funnier something is perceived to be.
* Sarcasm: It can be used ironically to express the opposite of laughter, such as when someone is annoyed or disagrees with something.
* Emphasize a joke: It can highlight the humorous aspect of a statement or make it more playful.
Remember: The meaning is often subjective and depends on the context and the person using it.
