A russiaboo is anyone who is obsessed with Russia and Russian culture. Very similar to a slavaboos but more in-depth. Derives from weeaboo because like weeaboo, a russiaboo is insanely obsessed with Russia.
They generally act like they are from Russia. Using shitty grammar and adding unneeded Russian words. You will commonly find them in international clubs. European based websites and a horrid app. Called ifunny.
They are usually teens and preteens. Who have no idea what Russia even is and believe Putin is the greatest human ever.
"Da! I am of Russiandecent. I am of going to joinings the rossiyan armies when I grow up. Slava ROSSIYA!!"
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.
