shoulderbeast 

To annoyingly watch over someone's shoulder while they are working on a computer. This activity is extremely distracting and is especially popular in the world of graphic design and advertising.

Dutch: pottekijker ("to watch someone's pot while cooking")
Brazilian Portuguese: papagaio de pirata ("to be a parrot on a pirate's shoulder")

I'm trying to work here, stop shoulderbeastin' me!
