It is an Anglicism for the "lift" night out, especially in males who try to seduce; although the term was extended to other situations without sexual goals, simply by pleasing, getting attention from another person. The etymology is unclear, but the one I like the most is the cat of the guru about seduction Ross Jeffries, called "Sargy J. Cat" , who went out every night to look for couples and was inspired by the verb to sarge. See you get an lift.
