beam down

To be sent to Earth via teleportation, as in stereotypical portrayals of aliens coming to Earth from their spaceship. This humorous phrase usually suggests that one is crazy. Did he just beam down from outer space? There's no way that plan will work! I know Harry's from the West Coast, but it's like he beamed down from Mars or something. He definitely does not fit in around here! A: "Does your mom seriously think the kids will go right to bed without a fuss?" B: "I know, it's like she just beamed down from another planet or something."
