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.
