An abbreviation of Oh My Dionysus.

Similar to OMG (Oh My God) it is used to express surprise.

The origin of the phrase is tied to BTS's iconic song Dionysus and is used by ARMY (the group's fans).
ARMY #1: Did you hear the news? BTS is coming to our country!
ARMY #2: OMD really?! I gotta try and get tickets!
