"RL" is often spelled all uppercase, but can be also spelled "rl". All versions mean the same thing. Just be careful not to type entire sentences in uppercase, as that is considered rude shouting.
Examples of RL usage:
- (first user:) Come on... let's run another dungeon for hour!
- (second user:) Sry, man, RL is calling. If I don't cook dinner for the kids now, they'll hassle me all night for macaroni and cheese.
- (third user:) LOL! RL is overrated, and you have too many kids anyways, hahaha
The RL expression, like many cultural curiousities of the Internet, is a part of modern English communication.
