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.
