The word "dumbrain" is tossed around a lot but many people don't know the real meaning, the real meaning to this word is a callback to the "big brain" and "small brain" but what it means is someone who is a weird person or just a little joke.

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.
