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!"
