What does DC mean in texting?

Hey there, could you possibly enlighten me on the meaning of 'DC' when used in text messaging? I've seen it pop up a few times lately and I'm really curious about its context and intended purpose. Is it some sort of abbreviation for a commonly used phrase or term? Or is it something more specific to a certain group of people or community? I'd really appreciate it if you could help me out with this mystery!
