Away from real life. A combination of afk and rl. It means to be not aware of your surroundings or to be too busy doing something else. Made up by Dano.
I mean it's pretty self-explanatory, use this word when something online or text related actually makes you laugh. You can use this in place of acronyms like "ROFL" "LMAO/LMFAO" "LOL" etc. If you find yourself saying "LOL" too much then "AFRL" is for you.
