The 'MAD' meme, often linked to the 'U Mad Bro?' catchphrase or classic rage comic faces, embodies the peak of online frustration and trolling culture. Emerging from early imageboards like 4chan and popularized across Reddit, these characters represent a state of irrational anger often triggered by subtle taunts or unfortunate circumstances. It is widely used to mock someone who is visibly upset or to sarcastically express one's own rage over trivial matters. Today, it remains a staple of internet vocabulary, serving as a shorthand for any situation that makes your blood boil or for calling out a 'salty' reaction in competitive gaming and social media.
