A truncated form of congratulations as stated; however it is a hollow form. There is little emotion, you don't care you are envious or it doesn't matter. You join the bandwagon of everyone else saying it.

The word is often used as just "grats" by itself. When it is used in this form is is surely a carefree statement.
