Today’s idiom is both an idiom and slang. When you tell someone to “get lost,” you are telling them to “go away.”
-I’m studying right now. Get lost!
-Lindsey told the reporter to get lost.
-Why don’t you kids go outside for a while and get lost. I want to relax for a while (Mom said to her kids)
There is one more similar expression with the same meaning – “Go fly a kite.” This also means go away, but it is a bit old fashioned English and not really used so much anymore.
