A 'Grdu' is a person that is socially awkward. A Grdu usually spends their days hiding in a corner on the internet, or stalking a person of their choice. Usually, Grdus are great friends but will inevitably cause your unstoppable doom in the long-run.
Wow that girl is such a Grdu!

Hey Grdu, hows it going!?
