RDO

RDO is short for Red Dead Online for the absolute peak that is Red Dead Redemption 2.

RDO is a place of infinite wonders, from the racist roleplayers and the tryhards to the seemingly boundless amount of bugs and glitches.

Friend 1: "Yo, wanna play RDO today?"
Friend 2: "I don't know... Remember what happened last time when I got stuck in the stable and you had to fight off tryhards alone?"
