1 If a football team stays up, it remains in a division and is not relegated (= moved down to a lower division) -- （足球）俱樂部依然留在原來的聯賽級別而沒有被降級
I stayed up to watch the Olympics on television.
The kids were allowed to stay up till midnight on New Year's Eve.
These days if I stay up late one night I'm exhausted the next morning.
