Someone who is of political right wing leanings, who is generally quite ignorant to any sort of positive change in the world. They tend to get upset easily by anything that rocks their comfortable privileged little bubble, such as vegan ism or gender neutral pronouns. They will rant how these examples are "uncesssary" and "political correctness gone mad", and will get infuriated by propaganda that is aimed to make them mad but too stupid to realise that it designed to do that in the first place.
"I can't believe that Greggs has started doing vegan sausage rolls! Its an abomination! The world has gone mad with these vegans and I for one will be boycotting Greggs forever!"
"Good grief Brian! It's only pastry. Stop being such a rightflake"
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.
