To "Steal the night" seems to be an expression that means having a great evening with a man or woman you might love.

This term was used in a popular scene in the movie Bloodsport (1988), but also appears in many more popular songs (i.e., Lookbook - Steal the Night).
Tonight, let's steal the night. Life is so fleeting but we will always have that one great night before you fought in the Kumite. I hate that you risk your health and safety, but that makes our time together so much more special.
