to tell someone to get lost, go fly a kite
Já estou cansada de você me perturbar, vá pentear macaco!
I'm tired of you bothering me, go fly a kite!
Ir pentear macaco ("go comb a monkey") sends a bother off to a pointless, faintly ridiculous chore — grooming an animal that will never look the part. It belongs to an old Portuguese family of brush-offs built on the monkey, alongside ir bugiar, from bugio (an archaic word for ape).
