Deskbro
Deskbro is someone you share a workspace with that you become friends with rather than just awkward coworkers. This can include cubical, offices or assembly lines.
I had a bad day at office. Garry, my coworker, came by and made an awkward joke which didn't help. Luckily, my deskbro Gabe noticed I was down so he took me out to an early happy hour to cheer me up.
