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.

Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
