to be full of energy, to be pumped up
Fulano começou o serviço com a corda toda!
He started the job all fired up!
The expression estar com a corda toda ("to be fully wound up") comes from the old mechanisms driven by springs and wound cords, such as wind-up clocks and mechanical toys. To run, they had to be wound all the way; fully tensioned, the mechanism worked at top speed and power.
