The 'Booker, Catch!' meme originates from the 2013 video game BioShock Infinite, specifically referencing the gameplay mechanic where the companion character Elizabeth tosses supplies like health, ammo, or money to the protagonist, Booker DeWitt. The phrase became a viral gaming trope due to Elizabeth's helpful AI and the frequency of the voice line. In internet culture, the template is used to represent someone being suddenly bombarded with items, responsibilities, or unsolicited advice. It captures the frantic energy of the game while serving as a versatile metaphor for sudden hand-offs, helpful interventions, or receiving exactly what you (don't) need at the wrong time.
