If pucca's answer doesn't relate directly to the question, the term "get," like other short words (e.g., go), has grown to resemble many kinds of action.
Most are quick... Do you get what I'm saying? Get the keys from the front desk, please. Get the phone. Get up, it's time to go. Get out of those smelly clothes.
Some take a while... Get well soon. Get going. Get accepted into my top choice university/job/group.
While some may take longer, even indefinitely... Get lost. Get smart. Get into space.
