The type of person who whines and whinges away very loudly in public about something that is utterly irrelevant to everybody in the vicinity. The person whose type of loud whiny voice you just cannot escape from - particularly if you trying to enjoy a meal in a nice restaurant, or if you are on a train journey, or somewhere quiet just trying to read a good book. The 'bleatchild' arrives and his or her voice then infects everyone's personal space for yards and yards around.
"That irritating bleatchild sitting four tables away from us is really going to spoil my meal - are you okay if we just walk out now before ordering? I just can't stand that type of voice!"
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.
