Not sorry 'bout it. Used when you don't regret your actions, thoughts, or feelings. Particularly useful in situations where shortened text is the norm (text, twitter, facebook, etc)
In a texting conversation...

James: Dude there's a hot milf that just walked into your house

Will: That's my mom you asshole!
