A fluffy-headed furball person who is consuming with their quiet confidence and composure. Well-centered member of society other than the fact that he/she is a stoner, alcoholic, a drug abuser, and well known by the police. Passive-aggressiveness is their weakness. They allow emotions to build up until something terrible happens and they may strike an object harder than their hand. Their smooth-talking and well mannered behavior can score them with the ladies/men and get them out of rough situations.
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.
