A brief acronym standing for "smile out loud." It was designed to bring about clarity to the reaction "
lol," or "laughing out loud," which no one actually does while reading text or
chat.
Although more accurately abbreviated as "sol," that would just sound and look stupid; and is often misinterpretted by non-English speakers as other words, such as the sun.
Intended to bring clarity of intention for
lazy people who can not actually type their responses. It reflects a positive response, without insulting the receiver with a "
lol". Can also be used as an adjective or verb, such as smolicious, or smoling.
