Little does he know, Sarah's traveling to the same resort as her ex - and she's bringing along her new boyfriend. English rock star Aldous Snow relapses into drugs and booze after a break up and a disastrous record. A., Aaron Green works for a record company stuck in recession. That day, Aaron's girlfriend Daphne tells him she wants to finish her medical residency in Seattle. In London, things aren't much better: Aldous delays their departure several times, plies Aaron with vices, and alternates between bad behavior and trenchant observations.
Meaning "to assign to or indicate a date" (of an event) is from c.1400.
I soon found myself laughing (sometimes lightly) as the film shows Aldous and his girlfriend and what goes wrong.
