hang on—(coll.)
1. continue smth. persistently; persevere with smth.:
- I really want to go to sleep, but I am going to hang on for a couple more hours.
2. keep listening on the telephone; not hang up:
- Please hang on for a minute while I find out what team you are on. I will let you know in a minute…
hang one on—(U.S. sl.) get very drunk:
- A simple statement to the barkeep —“I really hung one on last night”—was enough to get a little sympathy and a double Bloody Mary.
