The term 'opp' is shorthand for 'opposition' or 'opponent,' originating from Chicago's drill music scene in the early 2010s before becoming a global internet staple. It traditionally refers to rival gang members or enemies, but on social media platforms like TikTok and X (Twitter), it has evolved into a humorous way to describe anyone who mildly inconveniences you or acts as a 'hater.' From spotting an 'opp' at a party to joking about pets being the ultimate opposition, the meme uses high-tension street lingo to dramatize everyday social conflicts and personal rivalries.
