Anti-date 

A social engagement with an ex-flame, preferably in a romantic, candle-lit setting, where you examine the relationship in excruciating detail and discuss in unflinching terms... because you just don't give af anymore.

After-effects may include confusion, panic and general sense of overwhelmingness. These may be due to lack of sleep, but more likely because anti-dates are considered a bad practice by the general population.
