"Defenestrated" is past tense form of the verb "defenestrate." Defenestration is the act of grabbing something and lobbing it through a window at full speed, maximum velocity. It may also indicate dismissal from a higher status or power.
My little brother was playing Geometry Dash. On his 8,447th attempt on Theory of Everything 2, he defenestrated the family Guinea pig. Threw it out the window. Absolutely thundercunted it, nothing else to it.
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.
