That common "slut" (or whore) that will break the girl code and go off limits by dating your once lover. Even if you claim to be "Over that doushe bag" its still never recommended to date a girl's ex, if you do, prepare to be bitch slaped.
Cara: What the fuck?! Look at that home wrecker of a stupid slut that dates my ex boyfriend! What the hell does she think she's doing with him?
Bridget: I don't know... but let's beat the shit out of her till she breaks up with him. :)
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.
Person 1: Damn, Dustin already has a new girlfriend?! It's only been two weeks since he broke up with his fiance! I think he's a sociopath.
