The Delta P meme originates from industrial safety training videos, most notably a 2003 production by WorkSafeBC designed to illustrate the lethal dangers of differential pressure. The most iconic footage features a crab being violently and instantly sucked through a tiny crack in an underwater pipe, demonstrating that once the flow begins, it is often impossible to escape. This terrifying visual transitioned into internet culture as a metaphor for sudden, unavoidable disasters or being overwhelmed by unexpected responsibilities. It is frequently used to represent niche interests, sudden distractions, or 'point of no return' situations where an unseen force pulls the subject into a metaphorical void.
