In the spirit of Brony, "Bromaid" is the name typically given to adult male viewers/fans (regardless of sexual preference/orientation) of the Disney's "The Little Mermaid" franchise.
It is the combination of the words 'bro' and 'mermaid'.
Woman - "So you're a guy and you've seen 'The Little Mermaid'?"

Woman - "So, you're gay then."
Man - "Nope. I'm just a big ol' Bromaid!"
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.
