A girl whose attractiveness or weight forces her to declare herself a lesbian. Frequently occurs after a formerly cute chick becomes overweight or otherwise ages or lets herself go and finds herself losing the attentions of men that she once enjoyed. Proclaiming her homosexuality attracts a different kind of, but still welcome, attention from both curious men and adventurous women.
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.
