A lame ass excuse Dark Souls players use to criticize players who do not enjoy their beloved franchise.
Curious Gamer: Damn this game is so damn hard, it doesn't even allow you to adjust to the difficulty. How do I get past these 6 enemies who've just appeared not even 15m into the game?
An unconstructive phrase used by 500 lb. 4chan dwellers that is used as a way to make fun of lower skilled players in video games without actually providing any positive ways for said lower-skilled player to 'git gud'. It is less of a phrase meant towards positive intention of lifting someone up and helping them 'getting good', and more of a phrase of superiority used by virgins to prove that the 24 hours they spend per day in their room practicing a game is paying off and is worthwhile.
Mark: "Dude I suck at this game! How the hell can I get better at it?"
Melvin: "Just git gud man. Ez pz u suck lol. I'm better than you, you're trash, delete the game lolz you'll never be good at it."
Mark: "Wow, well that's pretty helpful. Thank you for answering my question so respectfully and constructively. That gave me a lot of deep insight on how I can improve at the game."
