1. L:)
An internet smiley used in chats and on forums to symbolize that something, or someone, is a loser. The capital L resembles one making a capital L on their forehead.

Joe (typing to Bill): idk, he is such a L:)
2. L:)
"literally" smiling as opposed to the way over-used :) For years people have been smiling into the ether without meaning using the traditional :) however, if you add L to the front it denotes your "literal" emotion as smiling!
Man I had a great time with you last night L:)

An emotion for people with unibrows.
