A person who stands around in grocery stores or other places talking to people and your trying to get by them, they acknowledge you behind them so they ignore you and just keep on talking. Or when your talking to somebody but they don't give you time to speak they talk over you because what they have to say is more important than what you have to say.

A portmanteau of carpe diem, a Latin phrase that means “Seize the Day!” and DM, which stands for Direct Messages. This word means seizing the day via DMs.
