Fourth quarter
In sports, fans online often refer to the fourth quarter of a game as "4Q." The fourth quarter is the final quarter of a game consisting of four quarters, typically football and basketball.
You will likely see 4Q on sports Twitter. The accounts that comprise sports Twitter are fans or sports content specialists (ESPN, Barstool, etc.), and they often use 4Q when tweeting about something remarkable or surprising. For example, a fan may tweet, "OMG, Mahomes owns the 4Q!"
You might also see 4Q on other social sites, in online messages and texts, and in sports blogs. Financial professionals may also use 4Q to refer to the fourth and final quarter of the fiscal year (although they usually use Q4).
Example
The Vikings have somehow won 7 one-score games in a row
That's cause they've scored more points than any other team in the 4Q!
How well do you know your texting slang?
4Q is vulgar shorthand slang meant to put down another person (the number 4 replaces the sound of the word “for,” and the letter Q standing in for “you"). It’s a quick, edgy way to deliver the insult without spelling it out, kind of like flipping someone off via text.
The term gained traction in the early days of online forums and texting in the 2000s, when character limits and the need for abbreviation made slang evolve quickly. People, especially rebellious teens and meme lords, may use 4Q to express frustration, anger, or sarcasm, especially when they want to be bold but not fully explicit. You will likely see it in texts, memes, graffiti, or online comments where a censored insult still packs a punch.
