The 'Smoking On That X Pack' meme emerged from Chicago drill rap culture, specifically popularized by artists like Chief Keef. The term 'pack' originally referred to a specific strain of marijuana named after a fallen rival as a sign of extreme disrespect. Over time, the phrase transitioned into mainstream internet culture, losing its literal lethal connotations and becoming a hyperbolic way to celebrate someone's failure or downfall. It is most commonly used in sports fandoms when a rival team loses a big game, where fans post images of people smoking with captions like 'Smoking on that [Team Name] pack.' The meme is a staple of internet clout culture and digital trash-talking, signifying a decisive victory over an opponent.
