A connotative acknowledgment of the word "lol" only applied in certain situations. Its original definition meant "There was an intention to laugh out loud but it was too awkward" (also written occasionally as "Llz"), used as a brief slang acronym to acknowledge the fact that there was an intention to laugh at what was said but for a some reason there was no actual laughter or excitement. ( reasons may include awkward, lazy, or drunk moments)

Other forms of Ulz include extended "u's", "l's", or "z's". Each ulz can be customized to your choosing.
