The word RNG usually refers to a person being either very lucky or insanely unlucky. It is commonly used by gamers and people in the social networks referring it as a compliment to him/her.
Kripparian: "My opponent just outlasted me from his insane RNG. How am I suppose to beat that?!"
Amaz: "I just got very bad RNG this game. That's why i lost. Let's try again."
Person 1: This is the most accurate gun in the game (misses) ok, bad luck lets go again (misses again) come on now (misses again) WHAT THE FUCK? MY RNG SUCKS
Person 2: lol I have one of the most inaccurate guns ever (hits and kills target) WTF? Guess I got good RNG today
Person 1 (misses 7th shot now, gets spotted and dies) FOR THE LOVE OF ALL THAT IS HOLY, WHAT THE FUCK?
Person 2: (kills 5 more people from long range) Wow, I'm great today
The RNG, short for Random Number Goddess, is the supreme being who reigns over all moments of chance in a Role Playing Game. She determines all hits, dodges, critical hits, stat gains, and item drops, among other things.
