(-: Meaning in Chat or Text Messages Online

The input "(-:" is an internet slang often used in chat or conversations to represent a left-handed smile or a smiley from the Southern hemisphere. This emoticon is created by using a hyphen, followed by a colon, and an open parenthesis, which forms a mirror image of the standard smiley face.

For instance, if someone says "I finally finished that project (-:," it means that they are happy and proud of themselves for completing a task. Another example is "It's a beautiful day today (-:" which indicates that the speaker is enjoying the great weather and probably feels good.
