What does get lost mean?

Get lost is a rude way of telling somebody to “go away” or “stop interfering” (e.g., “Get lost! This is none of your business!”).

If you get lost, it means that you do not know where you are while trying to find a location (e.g., “Sorry we’re late; we got lost on the way here”).

On a related note, if you’re finding it difficult deciding if loss or lost is the right word, bear in mind that “loss” can only be used as a noun.
