Acronym for the Smartest Guy in the Room, short for Smartest Guy in the Room Syndrome. The Smartest Guy in the Room has an above-average IQ and knows it; he or she grew up being the smart kid. A SGitR is smart enough to know that s/he's smarter than most people, but not quite smart enough to recognize when s/he encounters other people who are smarter. S/he defaults to the belief that because s/he is smarter than the majority of the population, s/he must be smarter than the people s/he's talking to. When a SGitR is in a room full of smart people, s/he'll continue talking down to and/or correcting them, happily oblivious to the fact that s/he's now in an environment in which s/he is not, in fact, the smartest guy in the room. See also mansplaining, Dunning-Kruger Effect.
"Ugh, at the party I got cornered by this guy who would not stop correcting everything I said about axon growth and myelinization for long enough for me to explain that I wrote the paper he was misquoting."

"I know that guy... Andy. He does that all the time, he's a total SGitR."

Serial Monogamist 

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.

Person 2: No, he's a serial monogamist...
