1. noun: General term describing someone of partial Irish decent who enjoys giving women (that don't actually want to date him) bruises. Typically the O'Fallon can convince any woman with low self-esteem that they should have sex with him, simply because they they are too afraid to say no. An O'Fallon usually has sex lasting no longer than 11 minutes. This is beneficial to the O'Fallon, since it never sees only one woman at a time. After sex, the O'Fallon's catch phrase is usually "This just isn't a good day for me."

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.
