Where does git gud come from?
Git gud is a deliberate misspelling of the phrase (to) get good (at something), based on an apparent "folksier" pronunciation of the phrase.
While we can find earlier, one-off instances of git gud, the phrase notably appeared in 2009 in online video-game forums and had spread by 2013. Google searches spiked in April, 2016, when online cartoonists latched onto the phrase's popularity in the gaming community in their comic observations about video-game culture.
Since then, git gud has become a common, humorous expression in gamer slang, which often features intentional misspellings for economy or rhetorical effect.
Who uses git gud?
As noted, git gud is especially used by the online video-game community. In this space, the phrase often insults a new player to varying degrees of offense.
At one end of the spectrum, git gud can be playfully used by an experienced gamer after they beat a new player. This use is a form of "smack talk," à la eat my dust, and implies the novice needs to take the time to get good at the game. This more good-natured git gud may also be used in video-game journalism and forum commentary about some aspect of a game or gaming culture.
On the other end of the spectrum, the git gud mentality has been criticized as ableist. As professional video-game reviewer Holly Green wrote in Paste in 2017, for instance, that gamers with disabilities cannot always achieve the same level of play as abled gamers.
Git gud is also more generally used as a shorthand for "investing the time and energy to develop mastery of a game." Gamers may jokingly use the phrase to indicate they are spending time gaming instead of attending to more pressing obligations.
Users familiar with the gaming expression may apply git gud to developing mastery in other, non-gaming contexts (e.g., learning a new language or how to read music).

[W]hy should gamers who have clearly worked hard and passionately to “git gud” have to endure gamers who have managed to cheat their way to the top?
