blackout date

A stretch of time — usually summer, spring break, or a long holiday — associated with repeated nights of heavy drinking, big parties, and the kind of chaos that leaves gaps in everyone's memory. Blackout szn is part warning, part celebration: it signals that a crew or campus is about to enter a period of legendary but hazy nights.

A large-scale power failure, and resulting loss of electricity to consumers.

A state of total social withdrawal, digital silence, or intense focus where someone cuts off all outside contact and goes completely dark — no texts, no posts, no replies. Blackout mode can also describe someone who is drinking or partying so intensely they are fully detached from reality. Used both to describe purposeful isolation and the chaos of losing all memory of a night.
